Hi,

Every exchange adding a new btc, eth, token address on the exchange website.
I think they need some private key to set the transaction on this websites.

So is this private key stored in a normal database?
And is this safe?

It is safe for whales who don't care much if they lose their coins. Rule is to leave only the coins you are trading with on the exchange, anything long term should be put into a proper wallet off the exchanges.

They can shut down any time and all your coins will be lost!

Yes I know.
But do they store the private key in a normal database?

you can google MT.Gox  :o and then research on ledgerwallet but if u want to trade cryptocurrencies ,mostly you can't avoid touching exchanges no matter how unsafe they are

never keep your coins or token on the exchanges exchanges can be hacekd any time  but not  the wallets it is not easy to hack wallets.

Generally, the private keys are kept by the exchanges stuffs or managers, there are risks that the exchanges will take away your coins, but I think some big exchange will not do that since they can make great profit to keep the exchange safe, instead of taking the coins away for a short time profit.

don't keep a lot of coins in exchanges

These private keys are handled by staff and key member of the exchanges. However I do not trust keeping my coins at any exchange as there is always a slight risk of loosing the coins that you keep in the exchanges.

Exchange use to buy and sell coins.If we purched coins send it in wallet. keeping coins in exchange wallet may be risk.
Because exchange may be hacking attact.

not safe you have a lot of risk especially  from hack attack

Exchanges were never safe. It's pretty high risk to stora at any exchange big amount of money. It could be closed/hacked/scammed any time. The absent of hacks in past is not a good reason to store your funds there.

I think exchange is safe. They have making money from own money, so they have spend lots of money to update their system. I think our coin is safe in their wallets.

Yes. More profitable is keeping the exchange alive then just run with coin belong to its user. So choose exchange also important.
Dont just user exchanger service that has no popularity.

Yes the private key are sfe but the exchange site are prone to hackers,reason why you are advice not to use exchangeas a means of wallet.

what exchange do you mean? Etherdelta and idex have private key on your own. I think they are safe, I used them both for trading eth token, It is automated exchangers. The worst at etherdelta is that the price is low at the token lauch at first week, I don't know why, I bought tokens from ICO, when traded in etherdelta the price is under the ico price. May be some bounty hunters or hackers dump the tokens.

It’s not safe to keep your holding on exchanges for long time even exchanges don’t recommend that most of the time I keep tokens in etherdelta because i will be holding private key of the account . But it is almost similar to keeping it in myetherwallet and sending to exchanges but bit easy and bit faster

Only local wallet can guarantee for your coins safety.
But you must be carefull, because your computer can be hacked also. Keep your private keys offline

Safe to an extent but do know they don't have to pay you back.

An exchange is a server that will store your informations. So your coins and your private keys of the site will be stored on this site.

If the site is hacked or down, or stopped, you'll loose everything on it. It's different from a wallet, that allows you to use an interface between your computer and the blockchain, but the wallet doesn't store your information, it's just an interface.

Exchanges shouldn't be trusted as a long term storage solution for your coins just in case, are they safe from being hacked and funds stolen? they are targets and because of this many of the larger ones will have very good security in place and a process for backing up funds in cold storage etc so although there is a chance I would be shocked if they were hacked easily.

Some exchanges are safer than others, but there is always a risk. It's not so much who holds the private key as whether the exchange gets hacked, shuts down, stops you withdrawing etc.
Best rule is just keep what you need for trading on the exchanges, everything else keep in your own wallet.

Exchanges are not safe! Depending on when you found out about Bitcoin, you might have heard of the infamous MTGox exchange. Long story short, it was hacked and all of the funds were compromised.. which in todays prices are worth several billions. The exchanges unfortunately store everything online, which means all your information is vulnerable to hackers, you should be very careful about trusting an exchange. The best thing you can do is to store only a small portion of your portfolio in these exchange and make sure that your main stack is somewhere stored offline. It's better to send a small portion of your portfolio and trade with margin, rather than risk sending everything. Some exchange are safer than others Gdax is doing great btw, but they are still vulnerable and there is always a first time for everything and everyone.

an exchange is as asafe as a website with your money on can be...

Not so safe that is why we are adviced to enable 2FA . Otherwise someday our accounts will be hacked into

They are not safe. Arguably that's the pond in crypto world where a lot of black swans live. But the life is impossible without them. So there are 2 possible issues when speaking about exchanges:
1) MTGox case. When exchange goes to nirvana. Only inspiration can make you remove assets before their trip begins.
2) Someone can steal assets from your account, when exchange itself is working properly. Use 2FA.
 

some days ago bittrex had a lot of problems and locked out users. but i think thye were user without an ID on their system

I think it is best not to keep any token exchange.The private key is always safe.Exchange can be hacked at any time but wallet cannot be hacked.Their private key is hacked due to the other's access to the fishing site.So i support wallet

It's not save they can decide to shutdown anytime

Yes, It's right.Etherdelta have private key on your own.I am a new user in etherdelta.I seen it when i start Eetherdelta first day.Need your own myetherwallet private key and address.when you start work with Etherdelta.So i think its safe for all just keep safe your own myetherwallet private key.

never leave your coin on any echange, the rules is simple. Past already show us how it is not safe...just tranfert on exchange when you need to trade...you will avoid bad things ! ;D

Those trading sites like etherdelta which is decentralized is not that safe. You can just create a new wallet there and send the tokens to ensure safety. Giving your private key is a risk, you can lose all your money. We don't know how they store those keys.

It's really up to the person that is managing the website because they have the choice to run with your money. Use the popular exchanges because they are least likely to run away.

If you are a long term HODLer - put your coins in cold storage.. also removes temptation to sell early. Exchanges are honey pots for hackers. Also, I'm distrustful of software wallets. Paper or hardware wallets are safest.

good exchanges save coins on cold wallets
there are different tactics to make it safe
i think that its risky to save your coins on an exchange, but its better than saving it on a wallet on your computer...

the best way is offline wallet or hardware wallet

I agree its really dependent to the person administering the website and the control of the security of the exchanges has to be their responsibility. The reputations of the website relied to them on all cases specially when there's problem occurs on some of the trading transactions. Most importantly the trader himself must be capable of doing more efforts of transacting his or her coins to safer sending and won't be able to share the private key to the social media to avoid any leaks of private information because its in danger of hacker attacks of lost of funds.

The brutal reality is that it is much easier to hack a private wallet than take funds out of an exchange(not saying it is not possible). Even so, its not being hacked that I am concerned with exchanges, its their shady behaviour that is scary.

People are naive to think that they will never get hacked - what are the chances right? right? Reality check, everyone is a target. Don't take the security of your coins lightly.

The chance that your private computer is compromised with a keylogger is a chance too great to take when dealing with cryptocurrency. Do you think your malwarebytes or ESET will protect you from all the dangers of the internet? Not a chance - even if it were miraculously to protect your PC, malicious software can be planted on your router, your printer.

The only, and I absolutely mean this, the ONLY way that anyone should store their coins is on a hardware wallet. If your coin doesn't do hardware wallets (eg. NEM), then seriously think about multisig wallets with the machines on different networks.

I hope that everyone reading this thinks twice about it, and doesn't have to learn the hard way.

Exchanges are like bathrooms.  Get in, do your business, and then get out.  They are as secure as you make them.  If you don't own the private key, you don't own your coins...

Exchange platforms are for exchanges. That is what it means. In other words, you will only put coins and tokens in there if you are making some trading, or exchanges of coins from one to another. It is not a storage really or a wallet in a strict sense if you are not going to use these coins and tokens for trading. You have to pull out these coins of yours and transfer them in a wallet whose private keys and passwords are with you. In the exchanges, the coins are not in your hands actually.

Chosce exchang with long times work and no need your private key! Deposit and withdraw fast and more gate way to do it! Price between Ask and Bid is same same!

With my experience i can say that it is still safe even they need the private key. But there are some instances that people do not take care so that they comment their private key. And it is the time that you will be hack or scam.

Best to avoid leaving anything on exchanges long term. If you want to buy and hold, it's best to keep it in a wallet. Obviously if you trade frequently, it going to be most efficient to leave in on an exchange ready to buy/sell when the market is right.  

It mainly depends on xchange how safe really is, but you can easy check it out. For sure the exchanges are not the banks, so your money are much more not protected. You should check if it is truth but i heard that few exchanges just stolen their user's money. So as I say people with huge amount of money should veryfied exchanges, don't dolh there a lot of money etc.

We sometimes need money and we can't simply wait forever. That's why we need exchanges. It's not only for professional traders. Once we get on the platforms, we try to make the best decission, to sell or to buy, or maybe, to hold it for longer term.

It looks like sooner or later most of the exchanges either get hacked or the owner runs away with the coins. I would not call that safe.

I usually transfer my coins in exchanges when i am about to sell them , i do not stored them in exchanges because it can be hacked at any time . But in my own wallet cannot because i have my private key in me.

According  my experience never trust any exchanger because we can't guarante they will be still existence. If you have a lot money just save them on desktop wallet. The famous  exchanger on the past BTC-E can be scammed too. So beware guys.

exchange can be used only for trading only because the security is more important. it would be nice if you keep the coins in the wallet offline to avoid hackers and crime.

Myethwallet is the safe wallet because private key with us. In centralized exchnages like polo and bitrex have private key with database. If a hacker hack then thiernwill be a problem..

You keep your coins in exchnages thats no issue but dont keep long time . Send to a safe wallet. Coinbase

Depends on what you mean by Safe.  Centralized exchanges don't offer Private keys to their  users.
The features you described are unique only to decentralized exchanges such as BitShares and Etherdelta.

of course they have some private key for each coins and i think they are stored in another database that will not the same with the normal database. they will make sure that the private key is safe from the attacker and they will protection to that key. i don't think that the exchanges will let the attacker can stolen the private keys because they want to make sure their business can run for a long time. and if we don't have to store any coins with them, we can move our coins into other wallet so it will be more secure and only we that know the coins.

Yes your right. Because not all the time time the exchanges is good. Sometimes they are hack. So just. Careful always.

Nothing is safe on the exchage.Hackers usually wont try to attack wallets as they know that that is impossible.They only attack exchanges to rob some.

some exchanges put your wallet in a cold storage. if you want to keep your money on an exchange for better protection you should use 2-factor authenticator and IP whitelist in an exchange and use a strong password.

Hacking wallet is not entirely impossible, you simply trying to fish some credentials data from the user you target, and you will have the access to their wallet just if it's not desktop wallet or offline wallet.
But I must agree, exchanges often get hacked by hacker, they find it easier to hack an exchange than wallets.

I think its not safe anyway to keep your coins in exchange for a long period of time. You can keep it there but not for long instead for awhile only mate so that you won't regret if ever there's an instances you didn't expect to be happen.

As far as I know of, exchange transfer coins between cold and hot storage. But you shouldn’t rely on an exchange to store your coins, it should be for trading purpose only. You do not control the private keys of the wallet and you never know when the exchange will be hacked.

Usually, the exchanges will use two-factor authentication and this is very safe. The private key is also quite secure because it's a randomly generated sequence and only you know.

exchanges were hacked a lot of time. just set up 2FA authentication. if u not going to trade then transfer coins to a safer wallet.

There are a few kinds of exchanges. One is the centralise exchange. Even reputatable centralise exchange is also risky. It can face attack or law issue.

Always keep your coins in your own wallet. Ideally, you should also keep your private key in offline storage. e.g. multiple USBs

Whether they store the private key in their database or not, is not really much of a concern since obviously they do.
But the fact that you can never have access to it unless they want to change to a decentralized exchange completely is what is important to note here.

Without any doubts, security wise, some exchanges are better than the others, but if you are thinking about having full control of your wallet or funds, then it is something you cannot get. This is simply more like having an online wallet.

Do not keep coins on any exchange wallet as we all hear regularly about hackers’ attacks. Use better the desktop version. Additionally make all operations in only the most reliable exchanges like Bittrex.

No trading platform is 100% safe. Hacker can do everything. The large flooring like poloniex, bitttrex have the best security today and that would be the better choice

Exchanges are not the safe place to keep your tokens and coins at. Exchanges can be hacked. Always place your cryptocurrencies in wallets. Wallets can not be easily hacked but be very careful with the private keys of wallet. Make multiple copies of it and keep them in different secure places.

If you want to trade on an exchange, use only the coins you can afford to lose on the exchange in the event of any hacking or scamming. This is because, most exchanges are centralized and you do not have access to your private keys, which makes you not to have full control over your funds. If anything happens to the exchange, then your funds are gone, as simple as that. Probably exchanging with your friends/colleagues/neighbors could be a quick solution here for avoiding exchanges.

It's safe to some extent,  depending on the platform

That's why we don't need to put much money on exchange site to avoid this. Only put bitcoins or altcoins that are for selling purposes only. If you have bought coins or you invest in bitcoin or altcoins. You must transfer it quickly to your own wallet where you hold your own private keys and yes make sure you take care of your keys.

I think the private key for each coin is safe because it is held by the owner or staff of the exchange itself. What's not safe is our account, especially if we don't use 2fa. I have the experience of receiving email someone tried to open my account, don't know where he got the information but Fortunately i have 2fa on so he couldn't break in.

that's right in any how we are the one who's also needed to create extra security with our accounts, exchange also have some risk but those who are
in the business for quite a long time already established or already made some extra measure in terms of security but then us, who's users are in need
of doing our protection too.

agree exchange sites like ether delta not be make it is a threat to all users right.. and besides what would they valid reason if in every transaction made we pay the fee right?
I think it is also a good business hahahaha to have a exchanger . I will be contented if i have one and it also helps the coins and other crypto to rise their prices
reputation is the bet for any threats or wrong doing they will do I think it is secure to data bases with much more secure and fast calculating machines that is to hack

never keep your coins or token on the exchanges because exchanges can be hacked at any time  but not  the wallets it is not easy to hack wallets.

How to hack? If you deposit token and sell quickly By ETH or BTC. Then there are no chance to hack. So its cool. and need more about secure and trusted exchange site.

It has been said on this forum over and over again that leaving your coin on the exchange and as a matter of fact anywhere indeed where you do not have a private key is not safe. Be it third party wallet or online wallet. Save your coin on wallet where you are in control of your private key.

Keep your own passwords
Remember to set Google verification

the advisable thing is that you keep the coins that you do not use in an external wallet and that you only have in the exchange the currencies that you use for trading since in the exchenge you do not have control of the private keys and in some case of hacking could take many risks , it is better to go for sure

All centralized exchange keep private key of all user so actually not really safe to put money in that exchange, but to minimize the risk use minimum 2 different exchange only for trading, and for long term hodl put all coin in personal wallet that we own by self the private key. And other important thing use all security feature in all exchange like 2 step verification, use private email address and always login from bookmark link to avoid phising site.

I think every exchange is safe as long as we can obey the rule and we need to secure our account, for example, we need to activate 2fa for our account, send verification to deposit and withdraw the coin, increase our level, and else. with doing this, I think we don't have any problem from the attacker although this is not guaranteed to make sure our account is always safe, at least, we can minimize and prevent our account from the attacker.

its best to take your coins off of the exchange

Why push your luck?  These exchanges are some of the largest targets for attacks and are also an open door for internal affairs.  I'd keep any large sums of coins off of exchanges.  It's a no brainer.

Exchanges don't have private key like myetherwallet but it has google authenticator for double security of your account. While enabling it you should save the 2fa code in case you lost your phone, it can be recovered.

Don't put your large digital currency on the exchanges, and keep your wallet safe.

While most of my holdings are in exchanges as I am a trader. I can say that those coins that you plan to hold long term should be stored outside exchanges. It should be stored in you private wallets where you have full responsibility.

Though exchangers owner may say that they are fully secured but it won't meant that we just let our wallet open all the time at their sites.  It seems to be that they are vulnerable for hackers attacks, knowing that they can't take all the responsibility of holding your coins safe all the time. That's why we should take care our own coins,  and we should never let others to have a chance of taking our belongings.

Ive personally havent had any problems. That said I feel like Binance is pretty secure whereas cryptopia and kucoin sketch me out. GDAX and the bigger ones are backed by US banks so those are really secure, but you wont be able to get alts on there.

It is never safe to keep your coins in exchange, keep your most of coins in a offline wallet and keep some of coins in exchange for trading purposes. When they got greedy, the exchange could be scam in near time.

I think not safe to hold a lot of coins/tokens for longterm in exchanges.
although hodl coins in some trusted exchanges there is no guarantee your assets will be safe there for a long time

The most secure wallet is hardware as Ledger for example. It's very hard to hack compared to online and desktop wallets.

Exchanges are not safe at all, even the top ones. So never hold your money there. Use exchanges only for trading and always withdraw your tokens in you don't plan to trade them any more.

We sometimes need money and we can't simply wait forever. That's why we need exchanges. It's not only for professional traders. once we get on the platforms, we try to make the best decission, to sell or to buy, or maybe, to hold it for longer term.

ALL Exchanges are targets for hackers, yes, but it is much easier to attack the users of the exchange, who most of the time cannot create secure passwords, and some do not use 2 Factor Authentication. If a user's email is compromised (very easy to socially engineer), it is easy for someone to do a password reset, and if they don't have 2FA activated on their account on the exchange, empty their wallet. Some users have their mobile phones connected to their email, and if someone gets hold of their phone, they can do a password reset, and also get the 2FA code on the phone to empty their account. Some exchanges allow apps to access user wallets on the exchange, so again, if the users phone is compromised, their account could be emptied.

Best Practice


-It is best practice to securely store your crypto in a wallet that you control the private keys for. A hardware wallet makes this very easy to do, and a user would have to have the wallet in their hands to move the coins.

-Apps & web based wallets are convenient, but with convenience comes less control and security, whenever a 3rd party can control your coins they are not 100% secure and can be stolen / frozen / confiscated. Period.

-If you are going to use an app on your phone to store your crypto, again, only use one that is primarily a wallet, and allows you to control your own private keys.

-There is a saying in bitcoin that goes "not your keys, not your bitcoin".

-If you are going to store bitcoin, or you need to spend bitcoin regularly

As far  as i know,trading site's for me has its own defense system against scam,and hacking system, because they also protect there  credebility toward the service to the costumer satisfaction,so thats why some exchange trading site need a two password security key to protect your invesment into there website,so for me my deposited  coin is safe in this place ,even im not using a nano ledger wallet,because its to expensive gadget for your investment coin.

Decentralized exchanges with a hardware wallet are the safest, but that isn't an option for everyone or for all coins. Always do your research before trusting an exchange with your money, and only ever have small amounts that you actively need to trade on them.  Otherwise keep it somewhere that you control the keys.

None, is Bullet proof

i agree my friend one should be very cautious where putting his or hers assets personally i neglect new exchanges and go for big ones like bitrex (unfortunately it is close now) binance and to be honest now i am using okex it it very efficient and i advice to use it.

I think nothing is totally safe against hackers, so do not rely blindly on the safety of the exchanges

All exchanges are not good. But there are few exchanges which have a great security, Like Bittrex. But you shouldn't keep your coins on exchanges site. If you are a day trader then you may apply for email verification and 2FA Verification. If you are a holder trader then better is hold your coins in your wallet, Not exchanges site. Good luck.

No,most of these exchanges are not safe because they are being attacked by these hackers,they are very prone to any attacks everyday that is why it isnt recommended to store your valuable coins in exchanges,it is also against most of these exchanges because they wont know when will their secuiry will be compromised by these hackers.

Exchange are not 100% save, do not use exchange site as a means of wallet to store token, leave on the coin to be traded on the exchange platform, I have lost some coin due to and exchange site been hacked, caution must be taken.

Most of the time it's safe to put tokens on exchanges, because when you log in to your account, you have Google secondary validation, and people have a hard time cracking your account.
Most exchanges put most of their tokens in a cold wallet, so there's no need to worry about that.

Many exchange operate different level of security checks and balances! You may not be able to really verify their claim, which mean you have to trust them blindly! I will advice anyone keeping all their funding on exchange to think twice. Don't put the fund you can't afford to lose on any exchange!

It would be nice to have decentralized exchanges, and if it were not possible to have the possibility to have the private key at the time of creating the wallet .

For me exchanges are not 100% safe in which anytime their website cannot be open anymore. There are lot of exchanges that are being compromised these days in which most of these exchanges are famous like Etherdelta and Parity therefore to ensure the safety of our coins we should only deposit coins that only for trade and coins for the long term should stay in our personal wallet or use the offline wallet like Nano ledger which is a hard wallet in which the most trusted off line wallet.

For me im 80% sure that exhange are very safe because it is the only thing that you're sure that your money is secure. Also when you exchange your coin its automatically operate in higher level of security. Although there some of them are suspicious so i suggest to you to trust only to those exchanger that on the top.

Any exchange is not safe. If you use this assumption, then YOU are safe, as you took measures. Otherwise... sorry. It doesn't mater how reliable exchanges are: you should assume no safety. Or in an unlikely event of a failure you will not be ready.

Are you really sure? There's so many exchanges that turned out to be scam out there and you can easily say that 80% of all those exchanges are very safe, then the safety and security of using hardware wallet might be 8000% for you.

Just my advice guys, whether it's decentralised exchanges or centralised ones, keep in mind that when your money isn't in your hand, it can be assumed that it's not safely secured.

Hey guys!

    - How safe is gate.io?
They have just listed my precious gem - Lympo - and I just wanted to know if its cool and safe or is it all yobit 'goes in, not out'
Cause they are listed on idex https://idex.market/eth/lym (https://idex.market/eth/lym) but its just 502s all day long..

Any feedback much appreciated because I'm really worried about the LYM tokens right now, invested big time, don't wanna burn down!

You should not import private key to any site. It is so risky. Some exchange site wants private key such as Etherdelta, Forkdelta, IDEX etc.
You can use other wallets which are not store our private key. Such as Bittrex, binance, poloniex etc. All time make safe yourself.

Exchanges are not safe place to store our coins and tokens we need to move it to the wallets if we want our funds to be secured.
But exchanges also has 2FA security which can save us from small hack attacks but it will be no use if that whole exchange get hacked.

They can not store coins in a closed mode. Each coin user must have access to their coins 24/7. If hackers gain access to the database they are accounts on their behalf make a withdrawal of coins bypassing the protection and authorization. We are always at risk. But that's life. Without this, it is impossible to trade.

Most of the exchange is safe but for long term it's not suitable to store our investment token, even exchange 99% is safe but still have 1% risk get hacked, better transfer to own private wallet (recommend hardware wallet)

Unless you want to trade multiple times a week in and our of different coins or in and out of FIAT then you should never trust your funds left on an exchange and always keep them in your own wallets.

You should try to avoid trading on small exchanges. Well-known exchanges such as Bittrex, Binance, OKcoin, these exchanges have a lot of people to play on them, you can rest assured that your funds in these Exchange.

They are relatively safe. Relatively mean that you can trade on exchanges and make money from your trading and as long as you do not leave your coins in the exchanges when you are done then you are safe. Using exchanges as a means of storage for your coins is not advisable and you are more likely to lose your coins on exchanges than in wallets which you own the private keys to.

No matter what, no exchange should be considered safe as long as they are centralized and the most important thing is to never leave your assets in them unless you have intention of trading them if you do not want to end up being screwed like the days of MtGox and the likes. The thing is that they may promise to be using a high level of security, but does this really guarantee anything much except to be at the mercy of the exchanges not having a loop hole and make them vulnerable to being hacked ? I doubt 8).

Yesterday i have setup f2a for my email, i suggest you should be setup verify mobile phone on exchange, when you or some one login your account, need send code verify to mobile phone and f2a on app, similar to your email, one case you will be lost is exchange announces they got hack =))

They are safe to trade with if that is what you are asking. What ever move you make regarding your trading on any exchange is your responsibility and they will give you your coins when you need it. It is important to know that exchanges are not wallets and should not be substituted and used as a wallet for the storage of your coins, saving your coins there can be risky.

It depends on which exchange, if the exchange is decentralized (for example, as an IDEX), then you bind your wallet with your key to it. If the exchange is not decentralized, then you use their wallets and the keys are kept by them and you risk them naturally, so if you plan not to trade coins for a long time, it is better to take them out of the stock exchange to your purses.

They can never be, as the only thing that is the safest is your cold wallet as long as your private key is intact. Exchanges are centralized and in that case, anything happening to the exchange negatively is definitely going to be affecting the users’ fund. The reason it has been clamored not to leave long term assets on exchanges is basically because of this and I believe by now, this is one principle everyone should have imbibed.

I am sure that the exchange will use everything to protect their site and their member because they want to give something to their member. and if there is any problem related to their site, they will do whatever it takes to give protection from the attackers. besides that, they will announce if they are finished to solve the problem or give any information related to their sites.

Crypto-currency exchanges are always reliable. This is the largest Binance exchange. Trading transactions can be done easily and quickly.

Generally, the private keys are kept by the exchanges stuffs or managers, there are risks that the exchanges will take away your coins, but I think some big exchange will not do that since they can make great profit to keep the exchange safe, instead of taking the coins away for a short time profit!!!

Agree with your point. Keeping the coins on exchanges isn't good. But still... if choosing just safe and reliable cryptocurrency websites, it usually would be the larger ones. To those you mentioned I would also add cex.io (https://cex.io/), they are pretty good in terms of security imo.

I think it is safe or not is not about where the private key is stored. Exchange is best practice to securely store your cryptos in a wallet that you control the private keys for. A hardware wallet makes this very easy to do, and a user would have to have the wallet in their hands to move the coins. If you are going to use an app on your phone to store your crypto, again, only use one that is primarily a wallet, and allows you to control your own private keys. Thus, you both control your private keys, so my opinion is secured or not depends on your control.

That belong to how the exchanges operate? If exchanges store customer's funds in cold hardware, it's totally safe.

I think it's a safe thing because until now no one has felt any loss with it because now every exchange offers high security to make traders feel happy and comfortable. so do not worry about it.

It is not really that safe to exchange your coins. Your coins might get lost. Before you exchange you need to be surr if you really want it and can take a risk.

No one centralized exchange can be resistant to hacker attacks. In the short history of the cryptocurrency existence, such incidents have occurred repeatedly, and in many cases, exchanges from their own pocket have compensated customers stolen money. Decentralized exchange cannot be hacked, mostly, of course. A much greater danger is the user's loss access to their funds. Can say that popular centralized exchanges are as safe as banks today.

Anyway, there are also specific cases of dangerous situations in decentralized entities, as happened a few weeks ago with myetherwallet, in which the DNS of google was hacked, but in any way, always the decentralized exchanges are perhaps not the most pupular but if the more secure. In such exchanges you should only have the tokens for the short-term trading.

first and foremost, I will advise you trade on good exchanges.  Tokens can be left on a good exchange when they are used for day to day trading activities. If you intend doing the long-term investment package, a proper and secure hardware wallet is recommended. The reason(s) is not far-fetched, An exchange can be hacked at any given time and your investment may be compromised leading to loss of capital. The least they could do is try to compensate their customers/investors. compensation can never be compared to your total worth of investment

Some exchanges are safer than others, but nevertheless I would recommend you to hold your coins into private wallets where you own the private key or a seed. Because there are always exit scams of exchanges.. You are safe if you store all on a cold wallet!

The trading floor is called safe. The floor is full of information, everything is transparent, there are thousands of participants in the transaction, the list considered potential

There is no safe zone that will cause the investor to not lose their money. People need to realize that while trading, people lose their money in order for the next person to make money.

Agree with your comments. I usually use 3 different exchanges like houbi, kucoin and bittrex. I divided my assets into three parts and stored on 3 exchanges. I think it's safe

Exchange is not safe for keeping your  coins, it is only design to trade your coins and keep of the exchange if you have no plan to trade it because exchange website are always the target of hackers.Exchange owner are the one who keep the private key of the address in the exchange.

You don't seem to realize that almost all the exchanges that got hacked, involved an insider. At the end of the day, a site might mean so well, but you never can tell of that one rotten egg. So never turn an exchange to a bank and leave only enough amount for your trading, which of course, should be an amount no more than what we can afford to loss.

Reshyrene just do not keep coins on long on exchanges! In any case, you can send from your wallet to the stock exchange and sell this business for one minute!

I try to not keep much coins in exchanges, even if it is my favorite exchange, reliable and time-tested. Thre is no fully safe exchange, so do not risk holding there your coins.

where it actually depends on each of us if we look at the crypto wallet everything is also safe they will use the code that is only the users who know and if there are some hacking possible errors are on the user he may give some address or key that is not intentional.

Exchanges too have private key for the wallets but they don't reveal that to us because they are holding our funs in the name of us we gave them such power,but not safe as we are keeping them in a wallet so if we want to store our crypto currencies safely for longer term then keep them in a wallet that provides private key.

None of them are safe, store offline.

exchangers are only as safe as you see them to be because measures have been put into place for users to make use of, but not all the users tend to apply all the securities put in place as a measure provided for securing an account by the exchanger.

I completely agree!

There are safe exchanges like Bittrex and Binance.
But, some exchange are not safe due to less security and prone to hackers. I don't wanna mention them.

Some exchanges are safe enough only to have a trade and go out. Since exchanges now are not totally hacker proof it is safe to store money not on exchanges.

Most of the exchanges are safe from hacks as they have proper security measures. The recent hacks which happened might be fake and have the involvement of exchange itself.

If you use the exchange to trade then how it is safe to holding the fund mate. I may agree that you can find the way to do the trade alone but will not be able to hold in any exchange for it mate. If you want to use the good exchange means please use the Binance, Bitrex, Bitfinix and Etherdelta.

For hackers you can see this is the easy way to reach your fund when are looking to hodl.
Please have some private key secured wallet for having your fund be safe.

I think that private keys exchanges are stored in offline wallets. For transactions, temporary wallets are used, which are controlled by robots. Undoubtedly, the owners of tokens are trying to keep the keys safe, hacking of exchanges is unprofitable for their creators.

It is not like we do not have decentralized exchanges such as IDEX, FORKDELTA (which is a fork of ETHERDELTA), but the thing here is that asides trading volume, I totally feel we are not just there yet and the available ones are not really giving out that much in terms of security and feel, as they are more like not that much usable in the real sense without even still being scared of not losing your funds. Looking at how EtherDelta has experienced huge attack in the past, it is still not much to rely on.

80% is a whole lot bro and sure, you may still be able to count on some exchanges safety if you can at least beef up the security of your own account, but even at that 80%, the 20% is still a lot if you have some pretty big asset in it.

What is the point, leaving funds in exchanges anyway if one is not trading? It is best to believe that exchanges are not safe at all, no matter the percentage you want to give them, and if all your assets are on an exchange, then, believe me, you have nothing at all.

Its depend on the security on the exchange, recently some exchanges were hacked and stolen millions of tokens by hackers but i heard some exchanges repay for traders back so you better choose good exchange.

I am sure that the exchanges will secure their site from the attacker and they will give protection to their customer. but this is not always guaranteed for every exchange because I see that there are still any exchanges that getting hack by the attacker. so we need to secure our account with the instruction from every exchange. so far, I don't have any problem with many exchanges and I think every exchange will give the best services to their customer.

Exchange will use encryption technology to keep Bitcoin, altcoin and user accounts secure. Some big Exchange also use cold wallets for large amounts of digital money. but You should use reputable Exchange

i do think yes its hard to hack wallet. Its really dangerous to put your coins on exchange for example in this month there was been 2 exchange on korea that were hacked and approximately lose 60million usd. But if you are traders it cant be helped. Just keep your private key safe.

Exchanges are not perfect and has weaknesses therefore exchanges are not safe. No matter how safe they claim there's always a possibility that traders funds are at risk, we have seen and heard a lot of exchanges hacked and shutdown so its advisable to store any amount of crypto for long term every traders and investors should consider it first.

Exchanges are never 100% safe. I only keep certain amount of coins which i want to trade with and keep the rest in hardware wallet.
Although old and good changes are less likely to scam but we can't ignore this fact that anything can happen and should perform the security measures to safe our coins.

I don't think you should ever trust your private key to any third party. Exchange or exchange, or offer to Airodrop.

I think to be careful in choosing exchange for trading coin. usually private key must be private no one who knows, because if private key leak, our coins can potentially lost. Such as etherdelta actually is quite save for trading as long as we are careful and not stuck with phishing website.

Without active bidding I try to withdraw money from the Exchange. There is a possibility that money can be stolen by hackers or employees of the exchange.

In my own opinion I will say exchanges are safe because they are the one that guides your asset for you and they keep safe your private keys, I see exchanges like bank because anything happens and you lose your coins, they will re-fund you for the lost coin.

You should endeavor to abstain from exchanging on little trades. Surely understood trades, for example, Bittrex, Binance, OKcoin, these trades have many individuals to play on them, you can rest guaranteed that your assets in these Exchange.

Exchangers are not 100% safe or secured. The reason is you dont own a private key and a lot of instances of hacking already happened. Be careful with choosing an exchange , if you really need to left your coins, just put some not all.

It is always possible, even with a very small probability, biggest exchanges can be hacked by the others. For the long term, it is not the safest way to keep your BTC and altcoins there. (saying that, I still keep them on exchanges for trading)

The truth of the matter is, most of these exchanges are not safe at all. Although, they've improved in their operations now by storing people's currencies in their paper wallet. The notwithstanding, I prefer private wallets than storing coins on exchanges. Most are subject to hack attacks.

I have been using the Bittrex exchange since the beginning of time, and I completely trust it, since for all the time I've been in it, I have never had any problems with losing my funds. However, you must adhere to the rule that it is better not to use the exchange as a means for long-term storage.

It is safe to do the exchange or the site itself.
just remember to keep your password safe and make a 2 authentication on your account for better security.
but please dont leave you coins or token there for too long as it is safer to be on a wallet.
exchange is just for changing your token to bitcoin or eth and not a wallet.

I never believed and kept bitcoin and altcoin on Exchange!
It's very safe, but what I'm worried about is how to manage and operate Exchange

well, it depends on what exactly you choose to work with , i think thatvit is safe if you choose wisrly

exchange can be safe, i think you dhould to ask for a advide of people from the communuty of the exchange

Decentralized exchanges (DEX) are very safe. It is very difficult to attack DEX, because you have no specific point for the attack ;).
Centralized exchanges are not safe, as you can see many recently hacks caused that many people lost a lot of money. That is why Vitalik Buterin said that DEX is the future and CEX will die in the hell.

I'm not sure of the security level of the exchange market, every exchange claims they are the safest exchange, I do not think there is a single safe exchange, if you want to invest, just use nano ledger and other offline wallet to store your digital assets, and if want to do crypto trading, use the market exchange that is very experienced, avoid new market exchange

It is wise to only put what you can lost on exchange but some have more than what you can imagine on exchange, because of day trading and a target set to achieve every day putting their funds on risk, it will be nice to save most of your token on cold wallet which is control by you, I think exchange should be regulate too, and should store all token in cold wallet .

there are a lot of it and i think you can find a lot of good things to benefit from the new platform amd new technologies

when you are only trading send your coins to exchanges. other than that keep your coins in wallet. normally exchanges can be hacked easily than wallets.

exchange can be safe and i think you can rptrusy it but for this you need to chooss the perfect echange and be sure in your decision

well, the wallet can be good and i believe in it as you can spbe sure your npney are safe within your wallet

I dont think exchange platform is safer either, because some of the time there are events of hacks and inside job. But compare to other internal wallets or perhaps mobile wallets, YES, I prefer exchange platform like well known ones like binance and bittrex.

there are no crypto exchanges that are completely safe from attacks by hackers even Bancor can also be hacked by hackers even though they claim to use a decentralized system.

 how secure they claim there is always the possibility that merchant funds are at risk, we have seen and heard many hacked and shutdown exchanges so it is advisable to keep any amount of crypto for the long term every trader and investor should consider it first. The exchange is imperfect and has weaknesses so the exchange is not secure.

You can't be too sure about the safety of these exchanges considering the various incidences about exchange. I think we just have to transfer our coins into our personal wallets and leave only the ones for trading on the exchange platforms

Indeed some of the exchange requires a private key to transact one of them etherdelta, exchange is the most frequently used, indeed worried access private key to log in, so be carefull or so that to be safe just choose exchange that only use email to access and avoid not to get caught web pishing.

I think so . it is safe, for sure they encrypt the keys and no way the attackers will not be able to seize the information

The choice of right exchange is the key to be safe with your money and in your work in crypto. I consider that you should check Binance, it is the best one for me.

The larger ones are reasonabily safe, as they do invest lots on money on being so, but the smaller ones, that´s a completely different kind of fish.

Its safe to keep your coins in exchange if and only if you have a verified security or 2fa intact but it all depends on the exchange also but our wallets are also another option if we are not sure enough of the exchange.its all a matter of choice

They are not providing private keys to us that is why Exchanges are not safe. It can be hacked at any time. When you are not trading, store your coins in a hardware wallet.

I don’t trust on the exchange, I only send my coin in exchange every I will sell and buy the coin. Never save coin in the exchange, because is very risk.

there are advantages and disadvantages of saving in the exchange and saving in the wallet. the advantage is we can send the coin in everytime we want to sell. the disadvantage is when the price suddenly increases at the high price, we cannot sell the coin because it's in the other wallet and we need to wait for the transaction is complete and it needs time before we can sell. but I think the exchange is safe especially if we can activate the security for our account so we can prevent the hacker to steal our coins.

If you are fast enough sending when price increase won't take much time in case it isn't a price manipulation or price flash with just little volume, that isn't a good reason for me to keep my coin on exchange because i want to sell when price increase i keep my coin in hardware wallet.

When you planned to hodl for a long term i think its better to keep your tokens safe at private wallet rather than on an exchangers. It can get hacked at any time or shut down because of no volume or trader at all.
You can transfer your tokens to the exchange right when you want to sell it, otherwise better to keep it in your private wallet

Don't leave all of your asset on exchanges if you want to invest for a long term. Even for big exchanges got hacked for couple of months ago. In my opinion, best option is to save it on cold storage for better security.  8)

The Exchange uses one address only when it will be sent to another wallet out of the Exchange. his example Ethereum:

merchant 1 removes Ethreum into Binance wallet
merchant 2 removes Ethreum into Bittrex wallet
merchant 3 removes Ethreum into Poloniex wallet

so all Ethereum is sent in 1 wallet, and it is certain that the exchange has its private key.

exchangers are just as protected as you see them to be on the grounds that measures have been established for clients to make utilization of, yet not every one of the clients have a tendency to apply every one of the securities set up as a measure accommodated anchoring a record by the exchanger.

With the supporting of the blockchain platform, your exchange with parter will be automatic saved and noone can change and delete it.
The hacker will be very difficult to access it.

I think it's safe as you keep money in bank. but saving coins in exchange is advised not to hold in the long-term, because the exchange can be closed at any time.

exchangers are just as protected as you see them to be on the grounds that measures have been established for clients to make utilization of, however not every one of the clients have a tendency to apply every one of the securities set up as a measure accommodated anchoring a record by the exchanger.

Well its not safe but you should not keep a lot of money in cryptocurrencies on tthe exchanges. Keep just the ones you want to trade and make sure its good exchange like binance or kucoin that will for sure return the money in case of hacks

do not keep assets too long in exchange that you have not trusted and not yet famous. you can save the assets in your personal wallet to make it more secure. for a secure exchange account complete with Two-Factor Authentication (2FA)

They're not 100% safe, but I don't think there's going to be much trouble on exchanges like binance.They keep security pretty high because they make good profits. Otherwise, their reputation will be greatly damaged. But as a general rule, keeping money on exchanges for long-term is not the right approach.

Remember when there was a syscoin hacked case through use API and binance has been taking an important act to reduce the noise from those are getting impact caused by that. Remember a lot of major exchange such as bittrex and polo have lost their credibility. polo has been investigating by DoJ

Do not put your money in exchange at a long term cos its not granted for safe keeping, it might be lost due to scammers sorrounding  in this business, better after you exchange your money put it unto your wallet for safety reasons they cannot hacked your private key unless you forgot it to log off..

Put crypto on the centralized exchange is not really safe because the private key of our wallet is own by third party and this mean we dont have any control with our money. There are already many centralized was get hack so really not safe to put coin on the exchange. Will be more safe to put coin/token in decentralized exchanges like Waves platform and Idex because they give the private key. And we you have to trade on the centralized exchange, for the better use more than 1 different exchange to be more safe.

One thing we should bear in mind is that exchange wallets are not for permanent safe keeping of coins. From past experiences, it is believed that exchanges are always under attacks because it hoards a lot of tokens. The best thing to do is to transfer your tokens from the exchange site back to your main wallet after trading with the exchange.

No exchange is 100% secure.
I could read that often enough and there were already some hacks in the last months.
Therefore you should not leave coins and tokens there longer than necessary.
But everyone should know that in the meantime.

While when you store your coins in an wallet you control, it's upto you how securely you operate.
When you have coins in exchange, the security of exchange too comes in play.
Though we don't have a large problem with popular exchange since Mt. gox and exchanges have increased their security and it's sometimes more secure to put the coins in exchange(2fa, otp, email verification) than having it on your daily use PC. Still large hodling sums should not be kept on exchange.

Each exchange has its own level of security. I consider that Binance is the suitable one because it has enough experience on the cryptomarket and its reviews are too good.

I don't believe in exchanges, I am the supporter of buying and holding only so such manipulation like this is not for me. But I know that so many people use it here without any doubts.

In no case do not give your passwords and keys . now a lot of scams who want to cash in on someone else's account . Stay alert . above all

General rule is not to leave your coins on exchange but withdraw them on your personal wallet so you have full control of them

Only decentralized exchanges need your private key like IDEX, ForkDelta or EtherDelta. Do not provide your private key to the centralized exchanges or you will loose your funds!

I think that no one can give a 100% warranty about safety of your funds on any exchange. But it will be not bad if you will use all possible settings for defence your security. The best defence, i think - 2 factor authentification with google App.

Spreading out the investments is one of the methods of making money with trading.

The name hackers can come at any time, if there is an opportunity then they act, safe and secure is not dependent on a strong database, if very very likely to be hacked.

It is safer to keep your coins/tokens in wallet you hold the private keys and if you need to trade, trade only with exchanges that are reputed to have a strong security. Binance does it for me.

Exchanges either centralized or decentralized are meant for one purpose alone and that is to exchange cryptocurrencies for other cryptos of fiat. People should stop leaving their tokens on exchanges because that is what leads to stolen funds when a case like the coincheck hack of earlier this year happens
Majority of people who's tokens are on exchanges are not traders so why leave your coins on exchanges, they should be in a wallet where you own the private keys.

The exchange market from its blockchain build-up, is always decentralized in the sense that it is devoid of a third party influence in the process of online transaction. By so doing, it ensures transparency, accountability and accuracy in the transaction processes between the buyer and seller. Although the exchange can be altered by cyber hackers whenever the exchange platform is not well built with sophisticated online security apps like the smart contracts or Dis centralized apps (DApps) that will detect any form of fraudulent activities in the platform.

i think there are no safe exchanger because even Poloniex sometime get DDOS or other attack. that is why we must keep maintain our asset by ourself. don't put all money in 1 exchanger and only what you want to trade in there

According to what I read at a glance about myetherwallet.com wallet that the website does not store our data in the form of private keys or addresses. My logic is that when a token in our wallet is attacked by a hacker, the website developer myetherwallet.com cann't return the token to its base address

If you are considering storing your coin on exchange, then choose a good one. Every coin stored there has the control of the management. So use your wallet instead of exchange.

It's as safe as it can be. Exchanges shouldn't be used for long term keeping on put the tokens you are going to trade. You'll only risk losing your coins to attacks. Have a hardware wallet if you're planning on holding your coins for a long period of time.

There's no exchange that safe it's on the user how to make it more safer like adding 2FA and more ask question that you are the only one who knows the answer. Well some of exchanger don't put things like this option to make it safer. Well its your choice to make your account safer on exchanges.

Exchanges Depend On Which You Are Using

As For Me I Prefer Decentralized Exchange In Which I Have Control Over My Crypto Assets

Exchanges are not the safe place to keep your tokens and coins at. Exchanges can be hacked. Always place your cryptocurrencies in wallets. :D

It's true, that if there is a hacker who takes your coin or money then he will not be held responsible for the matter and will not return the number of tokens you have. That's a statement that is valid.

Exchanges are not safe in terms of keeping your cryptocurrency at a very safe condition because the exchanges has a lot of money and it can triggered the interest of the professional hackers in the internet to penetrate or try to steal the money in the exchange. Exchange are the best for trading or making money but for preserving your funds, it is not safe.

You should never keep more coins than you are prepared to lose on an exchange. Not only are you vulnerable to having your coins stolen by hackers but you are also at risk of dishonest operators stealing your coins. You may even have your holding taxed by incompetent operators like OKex which recently took the profits from all the people who invested coins in derivative contracts to pay for the losses suffered from their inability to manage margin requirements. The only safe alternative is using a DEX where you still control the private keys.

It all depends from which angle you are talking from. if you are reffering to storing your cryptocurrencies on exchange, i dont think that is a wise decision to take but if you are talking from the angle of trading, then there is no way you can do without an exchange platform because that is where you will meet traders who are willing to do business with you. All i can say is that you do diligent research so as to choose reliable and dependable exchange platform.

never save tokens in exchange, because exchange is easy to hack and different from wallet. because the wallet has a smaller risk of being hacked because of stronger security in the wallet.

I like to put a small amount of tokens on an exchange so I can trade it faster.

I dont think exchanges is safe to hold your tokens. And this is only good for daytrading or buying some tokens quickly. I hold my tokens in my cold wallet and i monitor their prices everyday so i will be quickly sell them if they rise up.

You can added google authicator for safety your exchange account, always use the right website when you are access adn log in to your account. Never removed or change your google authicator because make your account is easy to heck and take your balance.

Bitfinex - While as yet charging expenses, this stage underpins many of as of now introduce monetary standards. Other than that, it is again one of the more confided in ones, despite the fact that their underlying money esteems complete tend to keep running on the lower side. They have anyway chosen to have some expertise in proficient exchanging so the insignificant record value must be more than 10.000 USD to begin exchanging.

Coinbase - it's difficult to discuss trade stages without specifying these folks, since they are the pioneers. Their charges are to some degree higher, yet they do offer both Wire and Credit trades, which can be helpful. It is restricted by nation and coins you can exchange here

These are the ones I for one trust and have had just positive encounters with. Try not to concentrate just on expenses, as in this unpredictable and test field the sky is the limit.

I generally try not to keep my coins and tokens on the exchanges. In my opinion, it is much safer to store in wallets. I keep coins on the stock exchange that I trade. The exchange does not give a one hundred percent guarantee of security and can be closed or it can be attacked by hackers.

I trust exchanges. I think they spend a lot of their resources to ensure a high level of security.

There is nothing like safe exchange for me;  even decentralized exchanges get hacked; only leave coins you want to trade on exchange; any coins you plan to hold should go to your wallet.

Exchanges can be really useful in some deals but I don't think that constant working woth them could bring a great profit. Trading is more promising here.

I have been utilizing the Bittrex trade since the very beginning, and I totally trust it, since for all the time I've been in it, I have never had any issues with losing my assets. Be that as it may, you should stick to the decide that it is better not to utilize the trade as a methods for long haul stockpiling.

it's better to chose big exchange ( reference on Coin market cap ) as Binance, Houbi, OKEx...it will ensure your money will not lost and if you face issue will has best support from exchange ( as deposit wrong address, withdraw ....)

Yeah, I trust the binance exchange, so I keep coins safe in the binance exchange wallet

I always select the best and known exchange because they has strong security background like cryptopia, binance, kucoin, hitbtc and more, be sure to add 2FA authentication on your security because it is hard to hack.

I think we should not keep coin in the exchange. Let them in the wallet be safer. exchange should only be traded in small quantities

Exchanges are good enough to protect our funds by storing them in  a cold wallet. They process any withdrawal request and send our funds back. It takes an expert to hack an exchange and these people can also hack our personal wallets if we mess up with things. It is better you don't make a mistake with your wallet.

This risk is high enough to save every exchange of a large amount of money. It can be closed / hacked / scammed at any time. Exchange is never safe and no hacking in the past is not a good reason to save your funds there.

I advise that one should split altcoins on portfolio to many exchanges because an exchange may be hacked and when you split all altcoins you would have confident that even if by mistake an exchange is hacked, it would not affect all your crypto portfolio. I am talking from experience.
Thanks.

I think cryptocurrency storage is the safest storage compared to other assets.
It's just that we need to be careful when logging into our wallet account, check first and make sure that the site we open is an official site, not a phishing site, and never give our identity or private key wallet to anyone.

Put crypto on the unified trade isn't generally protected in light of the fact that the private key of our wallet is possess by outsider and this mean we dont have any control with our cash. There are as of now many brought together was get hack so extremely not protected to put coin on the trade. Will be more sheltered to put coin/token in decentralized trades like Waves stage and Idex on the grounds that they give the private key. What's more, we you need to exchange on the unified trade, for the preferable utilize more over 1 distinctive trade to be more sheltered.

Exchanges are really safe because they compensate for the damage in case of loss. Information about your attachments will not be leaked, as well as your keys

Yes, I also expect this, because these are new technologies that will please us. I really expect this, but I understand that this may not happen. In my opinion, one of the promising coins is Bitcoin, Ethereum, because they are the most popular and prosperous.  :o

how secure they guarantee there is dependably the likelihood that shipper reserves are in danger, we have seen and heard many hacked and shutdown trades so it is prudent to keep any measure of crypto for the long haul each merchant and financial specialist ought to think about it first. The trade is blemished and has shortcomings so the trade isn't anchor.

How to secure exchange? In my opinion, you should not put money on the exchange. You need to use private and offline keys to prevent hackers from attacking. When exchanging, need to select the large exchanges, reputable to participate.

I think you are not worried about your exchange, because I believe that for us it is also very safe You can trade on the market, so you will also get more profits, seeing that the development of altcoin prices every day also increases better.

Everything will be safe, regardless if you are an idiot enough to make your account unsafe. Well as long as you have the ability to make secure of it and make a used of being responsible.

Some are safe and some are not safe. Before using anyone, do your research very well to know the genuine ones.

we know that poloniex, binance, and bittrex is the exchange that is safe because they do their best to protect their member and as long as we can follow their suggestion, our account will be safe too. every exchange wants to give the best service to their customer and they work 24/7 to prevent the attacker. so I think you can feel safe to register on every site and you need to activate much protection way to make your account secure.

I f you want to hold for long time then safe your coin in your own wallet otherwise good exchange like Binance,bittrex,okex are the best option for short term holding.

Exchange that has a good reputation will indeed reduce our anxiety and will increase our confidence to trade in the exchange. But still that the exchange has a high risk, to save assets in a very large amount, we better keep it offline wallet and move it to exchange when we need it. This is a choice because we have to reduce the risks that exist, the smarter we are in placing ourselves in a situation it will avoid us from the bad things that might happen.

Some of them are very secure and recognized, like localbitcoin, bittrex or crex24, those exchanges are pretty solid and nothing suspicious has been discovered... yet, anyway, my advice is always to save your coins in your own wallet, either buying your own S nano ledger or some other way to save your coins offline, just use the exchanges if you are going to trade a lot and try not to make them too big amounts, you never know what may happen and you can lose your coins easily.

There has been the issue of exchange sites being hacked. This puts fears in investors and some bounty hunters as to continue with the trading system on what.

I think your more at risk of having the exchange change rules mid stream and rip you off that way vs having a hacker break through the cod and algorithms.  I have had Huobi rip me off in this way. 

secure
I even sold a token and kept it in the exchange because the transaction was quite long, so I didn't have to withdraw it to my wallet account. after the morning I checked, everything was fine and did not disappear at all.

I think it is safe to leave your coins at exchanges because if it is not then no one would dare deposit and trade there. The advise is that if you hold longer, just get your coins out because you cant know if anything happens the exchanges suddenly quit you are going to lose your money.

For me, the exchange is a chance to earn and store money without any fear of losing money. The exchange is fully responsible for my funds

Exchanges are safe enough for you to carry out your trading activities but not safe enough for you to use them as a wallet to store your coins. You are more at risk of losing your coins if you leave them in an exchange than if you have them in your own personal wallet. The fact is that if you do not control the private keys to the wallet then you do not control your coins.

If you want to hold them for a mid-long term then wallet is the only logical option as the money will be stored in your wallet and only you have access to it and only you control it.
Storing the crypto currencies into the exchanges has many pros and many cons, if you are a daily/weekly/monthly trader then exchange should be fine but should take care always.

I don't save coins in exchange because it's dangerous. I prefer to save coins in a personal wallet because I save a PIN without having to know someone else. Storing in the exchange is potentially affected by hacking.

I don't think that every exchange is safe for store our coins. But there have some exchange with very high security. But still I didn't like to store my coins at exchange.

Those large trading platforms will not store the private key in the normal database, and I can tell you with certainty that the current cryptocurrency platform is not absolutely secure!

That is the reason why we need to take care our account and don't stay your coin in exchange. As long as you want to hold your coin put in on the wallet that can secure your coin.

To be sincere, exchanges are not safe to leave your Money on them. Many things had happened about missing of funds(coins) on different exchanges, that's why is safer to leave your funds on personal wallets and secure it with G.A. my thought

Exchanges are not really safe, that's why it's good to keep what you can afford lose on exchanges and make use of personal wallets mostly.

I agree with you. for example, take a stock exchange binance that very much values its reputation in particular security. and recently it was hacked twice, but it was not possible for the scammers to steal (as far as I know) and they will compensate them in case they steal. by itself on stock exchanges garbage and catch nothing

I agree with your statement Sir, there are couple of exchange sites who scammed their users withdraw all the tokens and shutdown the site and take away all the money.

The question is this: How to determine a legitimate and longterm exchange site?

Second: Do exchanges need to register for legalities to consider as legitimate and we can sure they will not scam people?

Their private key is stored in a normal database I suppose. But yes, you should use exchanges only for trading. They are not supposed to keep you coins. So be careful and keep your coins in wallet.

never hold a coin in exchange or you will lose it, currently exchange is very easy to hack, be careful, to hold the coin must be in the wallet

depending on where you exchange. My advice is if you want to trade and trade on the exchange, then you must use a well-known exchange, or at least you can see it in Coinmarketcap.

It depends on exchange. Some of them are safier and anothers aren't. At the same time Mt.Gox was the biggest exchange and it was hacked.
Also I heard that big exchanges attract more hackers.

There are definitely a lot of safety precautions these exchanges take in order to secure everyone's bitcoins, eths, and tokens. They would be immediately shutdown if they didn't, anyway. But I personally would pick the ones who are already known in the internet and not some shady exchange that no one stores on.

Adding those wallet addresses is to enable users trade with the coin. The only key required is your 2FA.

If i have to rate it to the scale of 1 to 10, i will give it 7. I often read/seen news from television and the internet about cyber crimes involving cryptomarkets as the victim. Millions of worth of cryptocurrencies have been looted by cyber criminals despite the company's self proclaimed maximum security on their exchange. That's what make it scary to deposit your crypto assets in the cryptomarket.

And for an extra precautions better to trade little by little first, observed how this exchange behaves and know all the information, there's a lots of exchange and they all have their own house rules, exchange mostly the target of hackers so you also need to focus with how this exchange work out
to prevent being victimized and if the exchange have extra security measures, experience always allow us to learned deeper and to analyze exchange
that can be trustful in the long run,.

Well, as safe as it can be. If you ask me, I think that exchanges are just as safe as wallets. Both of them have equal amount of risks attached to them, and an almost equal amount of security too. I believe that if you do not really worry about having your coins in your wallets, then you shouldn't also trouble yourself if your coins are on exchanges too. they are quite safe. Well, I am speaking for the ones that I use.

Yes, I think it is safe but its much better if you move your coins off the exchanges if you are planning to hodl for long term. When something bad happens to the exchanges, your coins will not be affected. They also have the power to remove your coins if they want to so its better to be play safe than be sorry later. Just make sure that your wallet is secured. BTW, I have tried to hold a coin on the exchanges for 3 months and haven't gotten any problems with it.

I don't recommend exchange sites for keeping of coins for long term. Exchanges are always under attack or maintenance and one can lose their money when the exchange is attacked by hackers. However, traders can keep their coins on exchanges temporarily.

Actually it is very safe if you store your coins in exchange wallet because usually they using cold storage to store all of coins and tokens.
But it is not impossible to be hacked, there were some exchanges have been hacked. So it will be the best for us to using our own wallet if we want to hold for long time.

we all know that exchanges is prawn to hackers it is not safe to kepp your coin in exchange , for me it is better to find another way like using our own wallet.

that is good advice. I also don't really like storing assets in exchange because they are very stolen. I only keep a few in exchange for the need to trade every day, the rest is indeed I will immediately draw it on my personal wallet. even though I cannot guarantee its security but at least I hold my own assets.

I don’t think any exchange is safe to store alt coins on long term. When dealing with digital assets there is always a risk of error in code that allows hackers to take advantage. So keep your token on a ledge if u want to keep them.

None exchanges are safe.
People have their exchange accounts stolen all the time. As you can be hacked from anything on Internet. When a hacker gets the access to your browser data, you are done. You accounts will be stolen along with your exchanges accounts.
Dont store coins on exchange. Withdraw them asap when you have them.

Based on how rating and famous of exchange market it self, many greatest exchange have higher and best quality of secure. You can hold and save your asset how long do you want, and your balance will be safe.

only the trust of users is the strongest factor for them, I use the exchange market for quick profits and in the end I will send it back to Mew or blockchain. there is no market that really has a full refund guarantee, they also panic when they lose their own assets, this is very disappointing because I see the thefts that occur are similar to their own conspiracies.

The adage in crypto market is hat if you don't have the private keys then you don't have control over the wallet. Most new exchanges are working on improving in security and keeping keys safe but the truth is that it is not safe to keep your assets on exchanges except you want to trade.

I prefer to keep assets in a personal wallet rather than having to be in the exhcanger. and if you really need finances you can make sales into the exchanger. now the risk is very big

Why would any exchange store their Private key in a normal database?

They will keep them safe in order to avoid any security issues. I do not think that they would like to compromise the security as they make a lot money from you.

But, it is always advised to only keep those coin on the exchage that you want to trade. The one you want to HODL should be transfered into a suitable wallet.

I agree with you because it is safer to store all assets in personal wallet rather than save in the wallet exchanger. as you said storing all assets in wallet exchanger is have a big risk and that's right.

Private keys are very important, especially for large and frequent exchanges!
Keeping the Private key safe is very important, I think they will use multiple layers of security for large transactions!

I have tried to store coins on exchanges multiple times and I haven't gotten any problems with it. What I am not sure of is that if its safe to hodl for long term. I only held my coins for 4 months and sold it the moment it pumps up. I also store them on exchanges because of the wallets being hacked a year ago. But I think that was fixed now so no need to store your coins on exchanges.

Crypto exchanges are not fully saved and we have read about many crypto exchange hacks, one need to be very carefull when using them and don't put all your portfolio in only one exchange.

Exchanges are always susceptible to get hacked due to security holes in their system, I think exchanges have both wallets hot & cold. They store user assets in cold wallet & transfers it to hot wallet only when the user tries to trade like when users place an order, but all exchanges may not support this facility. To be on safe side always keep your assets in your personal wallet for which you are holding the private keys or seed phrases, just transfer them to exchanges when you are willing to trade.

I think that the security of the stock exchanges today can only leave much to be desired, because such actions should definitely be regarded as something very, very insecure, I would never keep money on the exchange.

I will not keep large amounts of coins on exchange, even if  are the top exchange , always some hacker can find a way and maybe they will hack some users, i remember in past that binance, get some users coins selled for another coin , was affected users who hold bitcoin and have api activated, but binance fixed them and cancel all users transaction who has affected, and all get their coins back.

Some exhanges are more safer than others. And don't forget to activate 2fa if is possible.
So the best you can is to not hold so much coins on exchanges.

No exchange is 100% safe, there is always a possibility of hacking or fraud with any given exchange, but if we compared to risks, there are also advantages on exchanges like they give many other possibilities for earning or increase our assets on exchanges by simply trading, stop loss alert facilities and others etc. There is no doubt that wallets are more safe than exchanges, but they are very restricted and cannot give us chance to increase our crypto assets. If want to be less risky with exchange, try to not adhere to one or two particular exchange and try to make 5 or 6 or more depending upon self capability to maintain such number of exchanges.

Without security factor no exchange is safe and there are some big and effective authentication which are all exchanges using but google authenticator, sms  otp, email authentication are the best way to keep safe the account on the exchanges.

I think crypto exchanges are safe, but you are never safe for 100%. So I prefer to keep on exchangers only the needed amount for trading(never holding all money in one place)

I'm using exchangers almost every day, and I never had problems with it. First of all, you should choose a good exchanger like Binance or Bittrex. Next rule is not to keep all your crypto in one exchanger, it's safer to keep money on different platforms.

Exchange is safe to all if u dont give ur information to third person,and transfer ur crypto to safe palace,btw u got chance that someone can steal when u transfer.

I believe that exchangea in crypto was safe.If they grow that means they trusted for crypto people to trade their particular coins.

I use Binans and am very pleased. Strong protection and user-friendly interface.
I'm not afraid to trust him. In addition, you should not keep all the money in one basket. Therefore, distribute your money among several exchanges.

Safe or not dependent on the exchange developer, if the developer intends to be evil then all your accounts will not be safe. the account that we have should always be given additional security such as 2FA so that only we can access

The safety of an exchange site is of a greater importance and it is very sad to have your money locked up at an exchange site. Always in the best mood to get good and genuine exchange site to trade my coins.

Safety is not the top when it comes to exchanges a lot of them are very prone to hack which is why people are always advised to make sure that they never leave their coins on any exchanges. So you should make sure that you are only putting coins on the exchanges to trade but nothing else.

I believe that DEX are more safe now, especially when they use escrow system. Alot depends on DEV team but if project has a strong prof skilled staff-no worries. Don't forget about the volumes of the exchange.For example, I use LCS exchange but still store coins on wallet.Some people say you need to send to exchange but for me it will be always be too serious to store on exchange. But it doesn't matter I won't get my dividends, here you can send them either to wallet or exchange.

I think to be careful in choosing exchange for trading coin. usually private key must be private no one who knows, because if private key leak, our coins can potentially lost. if you want to exchange a save, can use etherdelta, there is a good market, the coins price is clear and safe in the transaction.

Exchanges are really very important in the cryptocurrency community. If you must use an exchange that requires your private keys, then you should maybe create a dedicated wallet for the exchange, one that doesn't keep much coins for you...

Developers constantly improve their exchanges. Nevertheless many of these services are not safe I suppose. There are many examples of hackers who succeeded in their desire to steal money. Users become victims all the time.

Your coins are safe unless exchanges are hacked. So never store your coins in exchanges wallets. Always choose the wallets that you know of the private key.
