Mistakes small or big that will cause us a lot in the future

[tech30338]

Have you made something that you think, will not be a problem in the future? here are things that might cause you problem that others ignore

Share private keys with a friend or family - sharing is caring as we all know, but these are the things that we should not share to anyone even close friend and family, since they might turn their back against us, when it comes to money, I have read a story of a person who trusted he's friend and family and he though he was hack by some hackers turns-out he's friend did it. it will also cause you friends and family when this things happen.

Remember password to your browser - This might be look alright since you are using the computer but what if a family use your computer, and browse then suddenly your computer , gets compromise, the data that  are stored there might be at risk, specially if there is like keys, or phrase for a wallet.

Allow others to use your computer as an administrator and not a guest user - Since we are close to someone we allow them to use our computer as a administrator user who can install delete on our computer, this is not safe, they might accidentally delete files or application in your computer, for security, give them a guest user for your safety, this is not a bad things since you don't want anything scary happen when you came back and login, and all your applications and data are gone, because they accidentally delete or remove it.

Storing sensitive data in your Email account - We have sometimes store data in emails, but what if the account were hack, all the data there will be leak and use, like wallet keys and seed phrase, some store it locally or in an external drive just to be safe , some write it on the peace of paper and keep it in a safe place.

Not using Authenticator or Security Verification for online transactions - although this are now required on exchange or some site, emails , some people forget to enable it on some sites that are not required to do so, like on emails you have a choice to enable it, because some are lazy to do extra step for security that is why sometimes they are the victims.

Always in a hurry - since we are always on the go, we tend to be working fast sometimes, since we are being complacent on what we do, always be cautious when it comes to things we do online.

Using same password on registration/ easy password to guess Some are guilty doing this using same password for registration is a very big mistake, also password that are easily be discover like birthdays etc., this are the problems i have read before and still they are making same mistake.

This are things that cause others big time, if you can add or correct me on this post please do so, more than willing to learn more,  I hope other newbies like me can learn something on this and don't make mistake.

Share private keys with a friend or family

You share your keys, you lose your coins.

Remember password to your browser

Don't prioritize convenience and comfortableness over your security. I don't want to sync my passwords, account information to Google, browsers just for convenience. I store those things on my own device and if I need to use them, I will retrieve it from my own devices, not from Google or browsers.

Allow others to use your computer as an administrator and not a guest user

Use your personal devices for your works, cryptocurrency stuffs.

Remember to set up strong password for your computers or laptops.

Storing sensitive data in your Email account

Don't store sensitive data on Google Drive, Dropbox, Azzure, Telegram or social media accounts.

Great list, especially the part of not getting complacent and trying to do everything in a hurry. If I can add something I will include;

• Not backing up your seedphrase,
• Attempting to remember passwords or seedphrase by heart,
• Not using an airgapped device or a hardware wallet,
• Not triple checking everything.

[Outhue]

Have no choice but to merit this post, well done OP, this is a well-crafted post that talks about what we think its fine but on the long run it can be unsafe and could cost us a lot.

Saving recovery seeds and private keys in email addresses is something people still do today, I talked to a brother to ask if he has gotten his hardware wallet since he has been talking about buying one for a long time, he said he hasn't, I asked why and he said he didn't need to anymore, so I asked him what could be better than a hardware wallet and he said he opened an email address for the recovery seed and private keys keeping only.

I was shocked, because this is someone who understands how secured hardware wallets are, he really believes that what he did is safer.

He said hackers can't know the email address because he never uses the email for anything else, that's when I burst his brain with many possible ways hackers can still get his email address.

There are many email tools out there, both free and premium ones, and they have this greatly disastrous way of finding and generating email addresses that are already in use. I am glad he listened and believe me, imagine what would have happened if we never discussed it.

Remember password to your browser - This might be look alright since you are using the computer but what if a family use your computer, and browse then suddenly your computer , gets compromise, the data that  are stored there might be at risk, specially if there is like keys, or phrase for a wallet.

On Google phones now, I can borrow a friend phone, check his chrome browser, all saved passwords can be found under settings, but it needs password or fingerprint if enabled, but do you know that it is possible for anyone around you to know your phone password if they are smart enough? It is possible, but I can't do that.

Not using Authenticator or Security Verification for online transactions - although this are now required on exchange or some site, emails , some people forget to enable it on some sites that are not required to do so, like on emails you have a choice to enable it, because some are lazy to do extra step for security that is why sometimes they are the victims.

But almost all noncustodial wallets do not support 2FA, the reason it is best to setup a cold wallet for maximum security.

This is a great list and very reminder not just to newbies but to everyone. I'd like to add about panicking. Like when something goes wrong and there's an investor who's panicking because he wants to transfer his assets quickly and exchange it on swap websites just like this guy[1].
The importance of having a 2FA is making your accounts and funds secure and making sure that you know where you're registering your information because there have been cases about sim swap[2] that has been a popular case since a few years ago.

Using the same passwords for all the websites we registered on can cause a big problem and loss, I did this with the majority of the websites I visited and bookmarked, later google security is now alerting me to change the passwords because a breach took place on one of the websites and have exposed my password, meaning that my accounts on other websites are not safe either, they have been compromised.

I got lucky with my cryptocurrency exchange accounts because I set up 2FA authentication, is not the hacker might have found his way into my crypto exchange profile and done their evil deeds

Make sure you use different sets of passwords per website if one gets breached it won't affect the others.

[Helena Yu]

In short don't store anything in any device where it's used to connect internet and try to be different on one site to another.

Another thing to reduce online attack are:

• Don't click random link
• Install adblocker and always check the domain name to prevent from phishing attack
• Avoid any altcoins e.g. airdrop, bounty, because it might compromised your privacy and security.

[348Judah]

Talking about the desired password combination to use as recommended, it is very important to always use bith the alphabets and numbers while choosing a password while addition of capital letters to one or two letters used is also a good advantage, a good password should have nothing less than 12 to 15 characters in combination for more strength against any third party guess, we should avoid using common words like our name and surname as password, birthday date, or cell number as these could be easily guessed by anyone.

Share private keys with a friend or family

This one risky that goes two ways; if one shares the seed phrase with just any family or friend it has huge risk. But there’s definitely someone in the family one needs to trust maybe next of kin to share seed phrase with or even a clue about it’s stored location in case of emergency like death.

Remember password to your browser

Although some see this as a tool to get access easily without repeatedly typing in password all the time but it is one easiest way for someone to get to your password

Storing sensitive data in your Email account

The easiest way hackers get ones datas really quick and easy is through phishing your email. So I also see storing important materials on the email as a lose security.

In short don't store anything in any device where it's used to connect internet and try to be different on one site to another.

Another thing to reduce online attack are:

• Avoid any altcoins e.g. airdrop, bounty, because it might compromised your privacy and security.

It is easy once you’re someone that hunts down all this airdrop and bounties then you definitely need to have a separate wallet than your main wallet your store your valuable funds or investments. As this will limit the risk of phishing. It is even advisable not import the two seed phrases on the same wallet.

How safe is ad blocker? Not all adblockers are safe because there are few that are closed source, even the ones that are open source are not entirely safe like we thought, the ad lock developer might decide to push malicious code one day, or imagine if the developer Chrome store account get hacked, there is the possibility that the attacker can inject a malicious update.

I feel like the best solution to this is to use incognito mode to access sensitive websites like Bank account and others, most browsers comes with incognito mode, you only need to activate them because they are always deactivated by default.

I agree at the same time I have use one of adblocker and its a bit annoying maybe I'm not to familiar with it, besides some have that and yet they allow something to run, without knowing it, next thing they know they are infected.
if you don't want to see logs of what you did in the computer like browsing to  site or anything use incognito, since there is no history to be log there or what so ever, in that computer.

Share private keys with a friend or family[/b] - sharing is caring as we all know, but these are the things that we should not share to anyone even close friend and family, since they might turn their back against us, when it comes to money, I have read a story of a person who trusted he's friend and family and he though he was hack by some hackers turns-out he's friend did it. it will also cause you friends and family when this things happen.

There is a saying that goes, "Only people you care about profoundly can hurt you deeply." Many people take this for granted, but it can be difficult to recover when we are hurt by a friend or family member. Trusting them can be a pain in the ass at times. I have witnessed numerous instances of people being tricked and cheated by their close friends and family members, which is why I have never advocated entrusting a friend or relative with a significant amount of money. No one can be trusted when it comes to money because, despite its occasional allure, it is said to be the root of all evil. I suggest that we exercise caution before entrusting our private keys to anyone.

Allow others to use your computer as an administrator and not a guest user - Since we are close to someone we allow them to use our computer as a administrator user who can install delete on our computer, this is not safe, they might accidentally delete files or application in your computer, for security, give them a guest user for your safety, this is not a bad things since you don't want anything scary happen when you came back and login, and all your applications and data are gone, because they accidentally delete or remove it.

This is a serious subject that people should pay attention to. Many people disregard these small security precautions. It's not a good idea to give someone administrator access to your computer because it will give them full access to everything, believing the owner to be the operator. Some users may delete files unknowingly or with malicious intent, so it's best to only give them guest access for security reasons.

Storing sensitive data in your Email account - We have sometimes store data in emails, but what if the account were hack, all the data there will be leak and use, like wallet keys and seed phrase, some store it locally or in an external drive just to be safe , some write it on the peace of paper and keep it in a safe place.

We should all refrain from keeping sensitive information like passwords, private keys, or seed phrases in our emails because storing sensitive information online is extremely unsafe and emails are also risky. In addition to them being hacked, saving them on email is like giving them to someone else to keep for you. What if an employee finds them and decides to use them to steal your assets? The ideal option to save any sensitive information is offline, in a location that only you can access.

[Ketesnuko]

Ad-blocker runs some kind of script in the background and some are so buggy as hell, they work at first and after a while you will start noticing some transgression in your PC, I don't like using them, my also confirm that Ad-blockers eat up more data because they work by running scripts and it's like opening a link in two places at the same time.

Share private keys with a friend or family

Sharing in the form of other things may not be a problem, but if it's a private key that concerns our assets then that's not allowed and we ourselves have to keep it secret, at least all relatives or family are in the same line of course from them there is always a different path then this shouldn't happen.
Our own private key that knows not a third party.

Remember password to your browser

Don't save passwords in browser I didn't do that because it's dangerous also if someone hacks in that we don't know then it's a big loss so simply don't save.

Allow others to use your computer as an administrator and not a guest user

It's not permissible for someone to use your computer because that would be a big problem too, it's better if there is a prohibition for anyone including family not to be allowed to use their own computer, as much as possible we have to be able to delete and reinstall what is needed and we have to understand about the computer then there is no need for the help of others.

Using same password on registration/ easy password to guess

Some people may use the same password to not easily forget so old passwords are easy to remember, but need to know this way is easy for hackers to guess we should be able to upgrade different passwords on different platforms and if necessary write down on paper or memorize it, I don't want to make the same mistake with the same password all so I've upgraded to a more difficult one.

• Sharing your private key is not a great idea at all, I mean you could just put it on a piece of paper or notebook for your family so that they can access it when the time comes, but sharing it with your friends is I think a big mistake because we're talking about investment and your money.
• I didn't see administrator login as a problem since I'm the only one using my computer and I do not allow anyone to use it. So just don't let them use your computer if you have important accounts or files.
• When you save your password to your browser or your email it wasn't really that bad, but it would be easy for hackers to gain access to your accounts if they infiltrate your computer. The same as saving your files to your email
• Using an Authenticator is an added layer of security to your accounts so it's always recommended especially for your accounts that have balance.
• I was one of the guilty saving the same password to some of my accounts, but I did change it, especially to my important accounts or accounts that have funds on them, I guess if it's just a random account on the internet you could do some random or similar password.

One of the most common hacking techniques is phishing which mostly happened through email messages disguised as an organization, sending malware, fake invoice, or asking a confirmation/personal information, etc. Probably just do not click anything that is suspicious on your messages or anything that is send by just some random guy on the internet.

[Fuso.hp]

Unknowingly we make some mistakes which we have to pay for all our life. I myself made such a mistake. I saved the account password in the browser while creating an account.  The device in which I had saved my password was used by some of my friends and younger brother sometimes, but some of them might enter my account and grab the password of that account from the browser, as a result of which I am in danger. Although it was a lot of trouble, I was able to recover the password of that account, but it may not happen at other times, so we should always be careful about these things.

[Chilwell]

Share private keys with a friend or family -

This is very dangerous but you have to share it indirectly, get a book-keeping and save your records their, who knows death can over come you and this can help family members recover your asset.

Remember password to your browser -

Get yourself a personal computer with a very strong password to the extent that no one can use it without your permission.

Storing sensitive data in your Email account -

It seem that email is not safe again, but you can also secure it that no one can have access it

Not using Authenticator or Security Verification for online transactions -

Authenticator is the best now for me.

Always in a hurry -

Always in a hurry doesn't give accurate answer of anything you want to do. Make sure you do your activities at right time to get a perfect result.

Using same password on registration/ easy password to guess

This is very risky because using the same password will allowed people get access to your system or website

[armanda90]

Not securing our exchange account with 2fa become problem for the future but today all exchange required it if want to withdraw or trading assets there, but right now the problem faced by all because not have recovery mobile phone how to access back later if main mobile phone loss or broken and 2fa application not possibility for accessing.

I faced this problem right now after my main mobile phone broken but have alternative after recovering and right now success log in back to my exchange wallet. I think for 2fa better check with application allowed register using mobile phone number and recovery or back up possibility with the same number.

[CryptoHeadlineNews]

Those are really vital points you listed above, and they are sure common mistakes people ignore which cost them a lot in the future, but I will love to add mine that some of the common mistake people do also include;
1. Sending a coin to a online wallet or casino without first taking into consideration what is the least minimum fund deposit is, and as such lose the fund and yet not receiving a deposit.

2. Leaving your crypto funds "investment" on an exchange wallet where you have no control over it for long term, and not using a non-custodial wallet such as "Electrum" that enable you have control over your funds.
