Bitcoin Forum

Hello there fellas,
I'm going to discuss something that keeps making me nervous. I'm that kind of a person who likes the decentralization, the privacy, the freedom and the equality in the financial world. It comes to my mind that these exchangers might someday be selfish, crypto is getting worthy and it will bring the eyes of the greedy peoples. Imagine that these exchangers grabs the trust of the peoples and then they start manipulating the market. The total volume in the exchangers is not stabe and peoples will never withdraw all their funds. Let's say that the amount of the holdings that an exchange have is 1000 btc, they could easily create sell walls of 1500 btc and peoples will buy because they trust these exchangers. What will happen then? Imagine that all the exchangers do this, what's your thoughts on this fact?.

I think all people like freedom) About exchanges i think they really do this, it confidential information and nobody cant tell for sure. Thare are video where Arthur Hayes CEO of Bitmex tell about this manipulation. I am not sure maybe it was fake, u need to check on youtube.

Few exchanges are very true with their volume, not all exchanges manipulates the market moreover news about this is already spreading and very soon actions will be taken on exchanges with fake volumes, exchanges like huobi or binance stands out among the rest,they always prefer to stay clean

Speaking about ghost trading, I heard https://p2pb2b.io/ did this before but they were using another coin. What happened to them? they rolled back the transaction before the users bought the coin and refund his money(they will make some sort of bullshit as an excuse). Some of them might do this, but all of them? I do not believe they dare to do that.
Not all traders are a fool, they know how to check exchange cold wallet and hot wallet. And calculating whether they have a sufficient number of coin or not, if they find out the exchange does not have a sufficient coin in their wallet. They report it to the exchange local government.

Have you considered the alternatives out there? You can trade on decentralized exchanges, eliminating the central part of all of it. Blocknet does the job, it's really easy to use once you get the hang of it.
Download the wallet's you need to store your coins in, in this example you want to trade BTC for BLOCK, so open and unlock your BLOCK wallet, and BTC wallet.

Open the DEX, and trade whatever you want, without ever needing to move your coins outside your own control (centralized exchanges).

Market manipulation is not new. I once read a news that said that almost all crypto exchanges operating today do manipulations to increase trading volume on their platforms. that's why we need DEX, with the DEX Platform manipulation in exchange can be eliminated.

I already know about BlockNet, it's awesome. The issue with DEXes is that the volume might be low for huge traders, the DEX could be safe and reliable but still we're facing the liquidity issues and it must get resolved by time. We can't keep trusting these fake exchangers with all the risks that we're facing. Just like USDT Tether could be printed, these exchangers could print btc and sell it.. They have big volumes and nobody could see that. The reserve of the exchangers will always have coins which doesn't get withdrawed..they could use that balances to manipulate and sell btc that doesn't exist. That is truly a threat to cryptocurrencies.

Personally, I also believe in decentralization and privacy, reason why I'll be glad to see more advanced decentralized exchanges in future. There are too many market manipulations presently in centralized exchanges and this has to be curbed, especially in those exchanges with low reputation. Let's just stick to a few exchanges with high reputation for now, since presently most decentralized exchanges do not meet up to expectations of crypto enthusiasts especially with regards trading volume / liquidity.

If you don't trust the mainstream exchangers then use the decentralized exchanges that's the solution to your worry. Manipulation sure is happening but sometimes we are not even aware of it that it's already happening.

Are you a huge trader? that could be an issue for them but there's a good number of DEXes that you can use if you are still worrying about the volume.

Nothing new, its been so many years and the market is being manipulated sometime.
Manipulation is a normal thing in every stokck or exchange.
If you are smart enough you can ride, if you have a weak mind then you will left alone

A weak mind?
Nope. I'm not weak. I'm talking in general and discussing the serious things here. My issue isn't with the non trusted or the low reputation exchangers. My whole issue is related to the BIG exchangers, the trusted ones. These exchangers could topup their account with 1000 BTC and sell it in the orders.. no one could prevent them, no one can watch them and especially no one could feel the manipulation. It could harm the crypto world and it will destory this beautiful concept.

That's what i'm talking about here, the funders deposited to an exchange isn't going to be withdrawn in total, just like the usual banking systems.. the total amount of usd in the world couldn't be withdraw in the same time.. That's a plus for the usa gov to print more usd without getting the eyes on the federal reserve back in time. This is going to take place here in the crypto field and even, it might have been practised before. No body knows, no body cares about this.

I thought that they can't because the transaction will be rolling back again consider about exchange site doesn't have enough funds to fill all of the orders that has already made by the buyers. Remember about the funds of exchange site will have always stored in the hold wallet and that's connected to the blockchain. Before the system will try to execute that and it must check total amounts that available in the hotwallet.
It's not possible to create such a fake coin order to be bought by the users but if that was about manipulating the trade use the bot or Mcap total and it's possible to consider about it has nothing to do with the blockchain.

I understood you clearly reading this than reading your thread starting post.

You are saying, they will be using the balances of each users like how we are saving money in banks and the bank uses it for investing making more money.
It could happen. But we have no control of that. All we can do is trust yhe exchange.
There are terms and conditions with them. Maybe you could talk to them and ask for a new terms which will prevent them from doing that.
But I doubt they will, worse you gave them a good idea what to do next.

It is already happening. I believe not only traders are using bots but these exchanges as well. I don't have the article but I have read an article about these exchanges offering to create volume for those coins that just hit the market so what will happen. Traders will suffer and many people getting rekt.

The exchanges can do that easily as they have power and control the market. But I don't think that all of the exchanges want to do because if they do that, they will lose the trust of the members. In the end, they will not online for a long time because the members will leave them alone. And if they have been caught for manipulating the market, they will lose everything, and even the owner can be reported in the local authority who's in charge.

If you are for decentralization, you should be happy if these centralized exchanges destroy their own reputation by manipulating volume. Users will lose trust on them and there's a high chance that they will prefer decentralized exchanges.

---

It's ironic that you are bothered by manipulation by centralized exchanges but don't bother promoting a forum paid by one of the exchanges that's been accused multiple times doing such activities.

This is what happens right now, cryptocurrency today are pure manipulation by famous individual in the industry. I really don't like what we have today, centralized exchanges really have the power right now. Decentralized exchanges should be the pne we are supporting to, take note that real decentralized not semi-decentralized.

What was conveyed by the OP could have happened but not too obvious because the amount is not too much.

CEX (Centralized Exchange) manipulation is not only trading volume but also news manipulation example when they say that exchange was hacked and there were funds that were stolen.

I myself was confused about this, because I was sure that people who worked on the exchange were people who are experts in crypto but this can happen and I thin that this is a manipulation too.
 

This kind of manipulation is the opposite of the previous type and aims to put additional pressure on the market during the correction, suppressing all attempts to rollback. This type is dangerous because the manipulator can provide the bear with a small volume throughout the entire trend, without breaking away.
In the case, when the market moves in the opposite direction, the manipulator can delete orders with a click of a button, thus leaving the market free to fall. At this time, very dangerous whales produce 180 degree turns and install the same blocks, but are made of sell orders, thus pushing the market down, where they will buy at market prices at very low prices.

Market manipulation may occur in all exchanges. What they do will definitely make us lose money and can also generate profits. Maybe that's what happened in Bitcoin in a few months ago, Bitcoin price rose very high, then suddenly dropped very far.

We can not do anything to avoid market manipulation. But I was lucky if I could follow the movement and quickly make a decision. I think it would make a good profit.

Yes, surely i'm a fan of privacy and decentralization. You're mentioning Yobit right there ? I'm not promoting yobit yet and i am just promoting a forum controled by them. Yobit does ICOs which are a legitmate investment because the investors are getting their selves in the risk and keeps investing. I don't know if yobit does manipulate but i never had any issue with my trades there. I am not defending anybody.. I am defending the usual risk. Think again about what i'm writing..it is a serious risk and issue. Any other solutions ?

Basically, one of the tactics that a newly launched exchange is to generate support and traders through changing their volume to look as pleasant as a successful exchange platform has. In myself, I can accept if and only if, they provide huge benefits to traders, there's no need to change the volume, they can actually attract traders with their own exchange token, just like what binance is doing.

I am almost sure that exchanges are manipulating every single data. They are manipulating orders, trading volumes, asset amounts and much more, who knows if biggest exchanges are doing so like Binance or Huobi. Thats why I prefer to trade only on such exchanges.

Unfortunately this is one of the many problems that crypto (and many other markets today) suffer from. Exchanges have power, and power ruins people.

I wish for a day that people learn to use decentralized exchanges (Dex') and they gain enough volume, but until then, this problem would exist.

Some trading platforms really abuse trading volume. This is mainly done by young exchanges that want to achieve an influx of users due to the high volume of trading. Maybe large and well-known sites, also engaged in similar earlier.

I am so happy that we have atleast Binance and Coinbase. These exchanges are last exchanges that are honest, provide true information about tradings and try to improve the experience from trading. Not to mention that they are helping the whole crypto world by creating various of useful products.

that was rigth they just want to be one of top exchange by using volume tactics which is actually fake . when you visit that exchange you will see that they just using bot for volume and the buy order for that  token is very low .

There is no exchanger that is safe in my opinion Because, regarding business of course the exchanger developer is only concerned with the benefits that must be obtained by their exchanger no matter what. New and old exchangers will definitely be straightforward to cheat the exchanger users if the transaction volume that occurs in their exchanger is quiet, so, they will enter the system, and then monitor the entire database of stop limit positions, buy orders, sell orders, etc. So with that data, they can create panic because their wallets have a lot of cryptocurrency quantities. Their goal is to create panic to trigger the buying and selling activities of traders, and they (exchangers) will benefit from our transaction fees.

Greedy people are already in the cryptocurrency industry.  You can see them manipulating trades, pumping and dumping in order to get profit from this scheme.  Several exchanges are also being accused by doing this, even Binance have an accusation of coordinated pump and dump of the IEO token that took place in their platform.  


This is possible but risky on the part of the exchange. Since a scenario where they sold out a BTC and all of a sudden, an influx of withdrawal comes in, they will surely on the deficit and will be unable to process the withdrawal creating doubt in their client.  Exchange will suffer more than gain a profit so I guess this won't happen.

There is no doubt the crypto space has made many things possible but on a reality point of view, it is the participants that are causing issues here and there; developers will create scam projects and so on. From the look of things, I don't think there is any exchange which is safe or genuine when it comes to volume; exchanges manipulates their volume so as to gain more users which in turn damages the trust people have on them. My simple advice is, trade with only your trading funds, any profit made should be sent to an external wallet no matter how small.

Many exchangers manipulate the market when they dump and sell their coins. Exchangers who involve in Pump and dump help in promoting a stock they hold and selling once the stock price has risen following the surge in interest as a result of the endorsement. This in turn causes a misleading appearance and could affect the prices

They can manipulate it anytime they want. It is somehow their power to create a strong and enough volume to their exchanges. I have know some exchanges that indicates that the coin that I am trading with has a volume but when I put my order something weird always happen, you may observe it in the trading history. There are many fake volume i  many exchanges now. There are few that it is real now.

These are the right questions. Don't make this idea over-important, that can cause depression. Think of other ways to withdraw the funds.

I think it's just a hoax, I'm sure that popular exchanges don't need to use such methods, because from trading fees alone they can get profits every day, so it won't be done with large exchanges such as binance, bitmex, and others.
I don't know about new / unpopular exchanges whether the reason they get hacked is because of manipulation?,or there are other reasons.

still relevant

Thanks for the sweety merits. Well, the issue is bigger than it looks like. The issue here is that the exchangers are having a lot of investors who trust them as a looking-like stock exchange market. These exchangers could easily create Bitcoins and sell them through their platform, these are inexistent Bitcoins but as you know, investors will buy because they are following the BTC price and it won't be an issue even if these exchangers sell 10000 non-existent btc, there will be peoples buying again and again. Just imagine the catastrophic damage on the market and the big profits they could make selling nothing in exchange of cash!
Peoples! , you shall rethink about the trust you're giving to these centralized exchangers, we're on RISK.

I think for all these issues crypto exchange regulations is a must just like forex exchanges or brokers are regulated to safegaurd investors and traders from scam or fraud. We know that most of crypto exchanges are already involved in manipulation either the way you have posted or by using bits that result in showing fake trades and volumes i do think that we need honest, serious and regulated exchanges for this market to grow nicely and mass adoption of this new market.

Even with Forex regulations most Market Makers will screw you because you play against the house. List of possible manipulations is endless.
The only safe choice in Forex was and is direct ECN trading but that always required large account (30k+).

In Crypto world decentralised exchanges sound like the best way to deal with the problem indeed.

Exchanges certainly could do everything Op described, which is why one has to pick his exchange of choice carefully.

What I would say, tho, is that as long as a trader can get the price he wants (and is a fair one across all the exchanges) it doesn't matter much if the exchange is playing around with the volume.  If they were to start fiddling with the bid-ask orders, that's another story. 

Regulated exchanges like coinbase, kraken, poloniex and the rest shouldn't have problems with manipulation, as that would mean the end of their businesses if they got caught.  That is not to say that they couldn't do it, just that they'd be stupid to even try.  Op, there is a place for paranoia when it comes to dealing with crypto, but if I were in your shoes I wouldn't let this concern keep you up at nights.  The bottom line is: if you're using an exchange and its working for you, and you don't think they're cheating you on order execution, don't fret it.

This can actually happen and I guess it does happen but they do it in such a discreet way, we can hardly notice or blame them. But I have heard exchanges manipulating volumes and increasing it to show others that their exchange is more active and better to attract people. I guess decentralized exchange platform are the only solution to get rid of those price manipulation being done by an exchange.

Old exchanges highly manipulated trading volume, not they are young exchanges because i saw that from almost 3-4 years in the crypto space. I have experienced about some exchanges those are huge daily trade volume according to coinmarketcap. I am talking about https://exrates.me/ it’s showing 2 million trade volume but when i am go to sell my asset than see there are no enough buy bid for sell my coin just remember that it’s how much manipulation.          

Not a new thing i guess, many big names are already doing this.
The only way out of this problem is decentralized exchanges. Although people don't prefer them much because big centralized exchanges have already captured the market by their huge volume and by providing multiple features.

The decentralized exchanges can't be regulated unless they are willing to do that if the gov't where they are residing starts to ask them to do so. The lowkey dexs can't be asked to do that, especially if the developer and owner are unknown. But I don't think many traders will go there if the owners are anonymous.

You stated that when you want to sell your coin on exrates there is not enough buy bid? this is different case, no buy order means the coin you want to sell have no demands, and one more thing, not all coins will have good trading volume, top coins like bitcoin, ltc , eth and stable coins are the coins that always have highest volumes on exchanges

We can feel this one, though the volume on a decentralized is low I also believe that this is a great solution for a more safe exchange. There are exchanges who are caught from manipulating the volumes, some are being fined for that but we still don't know that even the top exchanges I am sure they still manipulating the volumes of the trade especially on a coin that is not that active at all. Consider the exchanges not a safe wallet to store coins, always make sure that you have the control on your wallet.

Most of centralised exchanges manipulate the prices, nothing new. The higher their volume is the higher the potential that traders will be using their platform. I faced the problem of trading bots several times, and really irritates me. But price manipulation is real, and there is nothing we can do about it.

Well, I believe you. Unfortunately we can't do much about it if the cryptocurrency world is not united to ward off evil. Should we then leave the purging of filth to governments? I guess they should take care of the centralized exchanges while the community handles the decentralized stuff. The community tend to self-regulate things that are shared while things that are privately owned can hide behind the darkness of centralization.
Everything needs to be transparent not just the centralized exchanges. The Hypocrisy of this world is too much.

This is difficult for the exchanger in my opinion because the transaction holder is the customer unless the exchanger really wants a damaged reputation. This can happen if the exchanger applies leverage or margin trading but the exchanger still cannot become a market maker

Almost 88% of exchanges manipulate trading volume for better ranking. -MasterTheCrypto
Then they manipulate the market by taking the advantage of leverage trading. Bittrex is  a pretty good example of that. You must have seen how the website goes down once there is a significant price change. Lack of regulations is the biggest reason for that. But at the same time we don't want a third party regulations in cryptos. It is a double edged sword.

True decentralization can only happen when the currencies are being exchanged on decentralized platforms(exchanges) or peer to peer exchanges.
Only Centralized exchanges have the ability to manipulate their platforms and scam people. We have the ability to adapt to decentralized exchanges but just because most people are using centralized ones, the others are doing it as well.

We cant do anything regarding the market manipulation issue whether its centralized or decentralized it is illegal in any angle. The problem is no one is monitoring them and government power is limited or still not crafted, thats why these anomalous exchanges are keep on taking advantage of the current situation. I appreciate US for their commitment in regulating this young industry they should serve as role model for every country.

It's hard to happen now, friend, I have experienced it. I see several exchanges that have large volumes. but when I register and trade, everything is different. the market moves using bots, with a small total bid but runs nonstop. it makes me disappointed. and can't sell at the right price.

This is why we should not be blindly trusting in exchanges.

Exchanges don't even need customer capital to manipulate any side of the orderbook they want once they gain enough of a following. After all, they have full control over their own trading engines as well as the orders listed on their books. If they have sufficient influence their manipulation can flow onto the rest of the market through indices that contain their price info, etc.

Also, wash trading is another very common occurrance in the crypto scene. I wouldn't doubt if the majority of unregulated exchanges do it in order to fake their volumes.

Even regulated exchanges probably dabble in shady stuff every now and then. There is now guarantees. This is why DEXs are going to be awesome, but for now, just beware of obvious exchange manipulation.

The manipulation is being done by the whales and not the exchange. Manipulation is existing not only in cryptocurrency but also in other market. As long as you have a big capital then you can easily manipulate a particular market. Cryptocurrency market manipulation is inevitable because even we like it or not, it will still exist. The only thing that we can do is to better ourselves to be able to cope up with this type of challenge in our market.

I don't trust centralized exchanges primarily because they force all people to take the KYC. I have never understood the meaning of all this and therefore do not trust centralized exchanges. I certainly trade on some of them, but I do it without trust in their address and do not hold large amounts of money on these exchanges.

That is why a lot of people said that if we save money in exchanges, that means we don't have control about it. Maybe what they means is after trading we put it back to our wallet because nobody know what will happen. But about KYC, i think a lot of exchanges still allow people to trade without do KYC.

Most of exchanges that manipulated trading volume are exchanges that foster the population of bots.
The bots make the exchanges very crowd but it's just trading between bots.
And also, coinmarketcap is not an accurate source to see the trading volume, we should research the exchange itself to know the real volume

It's not far to happen even in a big exchange , like what OP was said if greediness comes up there's no way for any investors or traders to know what
the exchange plans in the next following days. They can do this kind of act and sucked all the profits that they can have while playing safe under their business umbrellas.

It's needs to have more awareness and careful analyze every exchange that you'll going to use. Having good reviews and check opinions from users will give you good insight to avoid making mistakes from using the right place to trade your assets.

The exchange manipulation is not new for me, a lot of recognition from some of the founders of exchanges did this in secret.
By creating a fake volume that ultimately makes investors fooled, this will be very detrimental to the users of the exhanges.
Because many people are greedy to take advantage of investor confidence. So from that there is a DEX platform to overcome
this problem.Or it could also be of us more careful in choosing exchanges, look for exchanges that have been proven to be trustworthy.
And don't play too much in new exchanges, because new exchanges are more vulnerable in this regard.

Yes, it's defenitely true. The biggest issue here is the money flow that will keep coming even if the fake-sell took place. It might cause big-medium dumps and it might cause a drop in the btc price or a pump just like the 30% pump in one day. Everything is possible nowadays, i wrote the subject just to express my fear toward these thoughts i'm facing. This is not a game of profits, this could destroy the economics of countries or even it might oneday cause a worldwide issue. Be careful, i'm in fear right now and my fears are getting stronger when i see btc doing some big jumps. These pumps could be organic but it also could be fake and the influence of the chinese president could be a tiny one.. It's a serious subject to discuss, i'm bumping it.

It is a common thing about volume trading manipulation by some exchanges to attract traders or potential users of the exchange.
However, this can be one of the ways these exchanges survive. I am sure that as long as this does not cause us much harm, it certainly won't matter.
The problem is that when various manipulations make a loss and deceive us as users, making us lose too much and lose money.

No one can really monitor the cex exchange manipulations. Unless you are part of the dev or team that runs the exchange. Many people already know how these exchangers operate and those pump and dump prices are clearly can be made if those exchange pull out one. Like the hacked in exchange, for exampls binance very suspicious right? That's why this market will be flagged as "wash market" very volatile and unfortunately not due to real market valuation but manipulation.

Manipulating the price is not a good way for promoting your exchange.
You can manipulate the volume but if they manipulate the price  of each coin .exchange  should be charge by the  law The exchange must be held and responsible for the incident of faking the price of a coin.

Manipulation of trading volume is indeed a mistake that has not recently occurred. The real purpose I also do not really understand because there are many possibilities such as, want to raise the prestige of the exchange, want to ride the prestige of a coin, or may want to cheat someone. Whatever the reason, I think this is a mistake that should not be done.

It will put the exchange in vain, if investors got disappointed with how the manipulations being executed trust will be compromise and many investors and traders will move away from that exchange. It's important not to deceive  traders who's using the exchange since they are the very life of the business. That's why doing DYOR is very important.

Exchange manipulations won't succeed if traders knows how to deal with this type of market situations.

This is not a mistake. A mistake sounds unintentional and is done without any ulterior motive. What is happening with the exchanges right now is outright cheating. The trading volume is very important in the exchanges' reputation because it is the foremost consideration that is being looked into by crypto traders as well as the projects that want their coins to get listed. There are many reasons why an exchange with the highest volume is treated as the top exchange. And many are cheating in this competition.

You mention the right one. Im ever trying to do kyc at p2pb2b but always failed and i dont know what exactly the reason. And i have some token already listed there but no buy order. I think so many market have fake volume and cmc still cant filter this case.

Im joined project a month month ago and the dev do this manipulation. The price is raising but no buy order. Before they do this not much investor interested with this project but after people know the price raising at cmc they joined group. I think manipulation also they use for marketing strategy.

Yes, that's what I meant by 'cheating'. Thank you for correcting it. But I think 'mistake' also includes negative actions that are done intentionally as well and finally known by others.
This fraud makes the world of crypto considered unstable, pump & dump, manipulative, etc. Though exchangers are a vital part of the exchange between crypto or crypto with FIAT. Hopefully, this can be reduced in the future.

The deception was clearly seen. Stay away from such coins or you will be eaten by them.

I think if all the exchanges manipulate like that it has become a very terrible thing because it can provide losses for many traders who make exchanges at the exchange place, hopefully what you think is not happening at the exchange so that it can make the exchange stay safe and comfortable when trading.

That could be a deliberate manipulation between the dev market exchange and the project dev.
And very clearly the goal is a marketing strategy, the dev want to show everyone that the project/token/altcoin is legit but in the end when we have bought it in that the market, we are fooled by their wits. full of manipulation, fake volume, fake order wall. it happened on some market exchange.

Not all exchanges do such manipulations, so many exchanges have their original volumes and really crowded markets. I've seen a new market where there is a trading event and I follow it.
The market is quiet but strangely the transactions continue to run I think they planted an automated trading bot in order to lure traders to trade.
But I am sure, surely people will choose a large market and have a good volume for them to trade.

I think this is not pure manipulation, because the distance among buy and sell orders can be very far (this usually happens on altcoin that have low volume). Except, if the order book does not change, but the trade history continues to run, definitely there is a manipulation. Cases like this can be found on the p2pb2b exchange.

It's an unethical practice which is used by so many mid and low level exchanges and the real reason behind this would be to show fake volume of a particular coin and sometimes they just try to increase the price of a particular coin by doing this due to some sort of agreement between the developer of coins and the exchange. Also they want to attract users by showing fake high volume which is just a bot trading and now they are losing their user base because of these cheap tactics.

No problem my friend, i use binance and huobi exchange alot because they are fair and transparent, if i notice any shady thing about them then i will stop using them, the truth about decentralized exchanges is they lack volumes and good liquidity

It is a reality that whales can really manipulate the cryptocurrency market. Thats why there are shitcoins that keep pumping because of the huge portfolios of the whales have.

Unfortunately, there are such, decentralization is the main thing that we have in the crypto market.
Now we have a situation similar to the banking system, when we ourselves transfer our funds into the hands of a third party, an intermediary, on whom we rely on integrity.

But this is just a business, and as in the case of banks, also in the case of exchanges, if everyone abruptly starts withdrawing their funds, withdrawing them from the exchange, this can cause a collapse of the exchange if it does not have enough liquidity. Who knows how the exchange manages our funds when we bring them to the exchange.

But alas, there is little that can be done now, traders cannot refuse large exchanges because the analogues of the center of Lysed exchanges do not provide sufficient functionality and liquidity.

Like what you said, manipulation is normal in all types of market. Every market have a big player who have huge amount of money. They posses power that can influence the price of a certain coin or stock.

Some Forex brokers are also culprits in price manipulation reference forexpeacearmy.com where series of scam and manipulation are made against them I was surprise that these abnormalities is also embedded in crypto exchanges I believed this is an eye opener to newbie to research well before depositing or investing in any crypto exchange I know two or three that are very trustworthy and credible thus weak minded should be very careful.

I think more like a market monopoly, but it will be difficult to stop because they have great power and can create hype on the coins. the most important thing is you should not be affected and trapped in losses, because the hype can quickly grow and fall. so it is better to see the existing conditions

manipulate is needed in exchange to increase its liquidity. exchange needs money from trader/ investors fee
there are many actively trading, the more money exchange get. that's why exchange must make market look sexy to do trading
to make market look sexy, exchange must do pump and dump. that look an evil, but it can't be helped

I am of the opinion that exchanges that manipulate are more than those that are exhibit straightway or real trading. They have greatly outnumbered them, that you might find it hard to identify those that still make it real, although they exist.
Also, these set of exchanges that manipulate can most time be well known and today some of them have crashed. Those that still exist are only trying their best possible to remain afloat.

Sure they can do this but I don't think all of them will make their hands dirty and sacrifice their reputation for it. If they try to manipulate large amount of data, some people will eventually notice and can produce bad image. Though they can also manipulate lowkey and subtle. It is possible that there are strings that they can pull but I guess they can only use it when they're desperate or if the market is too depressing or cold.

Therefore, in my opinion government regulation is needed. Price manipulation is a prohibited act in any market because it can harm consumers. In addition, with strict regulations, exchangers must guarantee the safety of customer funds and replace them in the event of theft or fraud

I got a little heads up for you, it already is happening.  Unfortunately in crypto you still have to expect the worst but hope for the best.  This I would imagine would be more prevalent where there is little to no arbitrage availability with a coin.  So if one exchange has exclusively  secured all the volume of a coin I would recommend to stay away because greed usually wins out and its bound to be manipulated

You hardly have to wait for 'someday' to see this, I'm convinced that they are doing so already, and that they have been doing it for a long while now. Some of them got busted, others are subtle enough, but they are doing it alright.

Be wise in choosing which exchange you will use because some of them manipulate the prices to make some coins look good. Comparing the prices from different platforms help a lot to decide well. Big exchange platforms will least likely to attempt to manipulate the prices and trade volume because there are a lot of eyes and their reputation is at stake. Small and new ones however are difficult to determine or if they have hidden agenda, only experience can verify.

Yes its possible for the exchange to do price manipulation because they hold a huge amount of crypto but it will be very dangerous for them since they are following some regulations so if people found out and expose them with proof then they might be put on jail especially those popular exchange which i think that only scam or fake exchange will have the guts to do this.

I do not think this occasion might happen with top cryptocurrency Exchange, it is only possible for small ones in case many people make withdrawal requests at the same time. If you afraid of such situation, you would better hold your funds on your own wallet.

While I am just hearing those volume manipulators, fake volume, etc, those exchanges who are doing that are those who do not have reputations to be take care of. Unlike those old, trusted and established  exchanges. I don't think they can do that in exchange of losing a good reputation, they are dedicated and honest to gain more users.

On the other hand, this  statement from this website  (https://medium.com/crypto-integrity/fake-volumes-in-cryptocurrency-markets-february-report-fec9329f1f98) that shows reports and write those not so known cryoto exchanges that manipulated the volumes to acquire some btc.

Manipulation has been a big issue in crypto trading, so much power and trust has been given to centralized exchanges indirectly, hence you are right that someday they might do something outrageous of that sort (even though setting up a sell wall of say 1500BTC when traders' funds are 1000BTC is a hyperbole per say). If everyone can decide to choose DEX over CEX, volume will pick up with DEX and hence liquidity will be achieved added to security of DEX.

There is possible because usually crypto exchangers now are all centralized and easy to manipulate by the owner. But I guess those exchangers that have a shady activity will most likely doing this. Probably those well know exchange site will not ruin their reputation on this shitty work. We can easily spot those making manipulation on their own exchange site. If we were afraid this just holds for the long term and don't trade.

Although, there will be continuous advocation and campaign against manipulations on exchange, but i am in doubt if it will be totally eradicated. The reason is that, there is yet no regulation against such, except in they are operating in locations where they are bound by regulation.

If we can follow the game of whales we can survive in this current market condition. Just one thing that we must to held, don't panic when market movement surprise us. If the market move more than 10% in just an hour, it must be a group of people doing mass selling or mass buying.
So, don't get tricked and don't be FOMO, we must confirmed and browse about the news about the coin before we buy them, or we should wait for a correction to check if it's a sudden pump from whales or not.

as exchangers work on customs of decentralized with the blockchain system the reference of transaction might be available on records and offering option as trader to manage with the deeper on measure to returns with decision as expending funds on authorization.

the exchange has conducted a fake exchange volume to increase their volume. This is a game to fool trader. I prefer local exchange indodax famous example in Indonesia and has a good reputation and has a real volume you can choose a local exchange in your country, which you can trust.

I wouldn't buy something based on volume anyway.  I was talking merely in the sense that if one exchange has all the volume or only listing of a coin I would stay away
  It's too easy to manipulate.  Now if there are 10 different exchanges than It would be slightly harder (still obviously possible) to manipulate a coin because arbitrage exists and would stop any manipulated pump or dump
