Tagged the exchange or what site it's here in forum so that everyone knows that its totally not secured for storing money. Indeed its so easy to give feedback nowadays when it comes such things, Wherein it's up to you if you have free time to do it. Because hackers always exist when they found hole to attack any sites. So it's up to us how to avoid it.. What i mean if you don't have time to speculate or make research before buying bitcoin or any currency then it's your fault. These is based on your question actually..

Exchanges should solely be used only when if you want to trade. Using it for the purpose of storing is a big no. Binance was hacked, even though they were still able to repay it, there is no certainty those occurrences will happen again. Say it the hacked amount is bigger or people lost trust to them. AFAIK, they recovered it from other people fee trade, well, that only possible if people still trusting them.

Anyway, Instead of trusting a third party to have securities measure for your coin, why didn't you achieve the security by yourself and for yourself. Having a self-custodian wallet also give you a financial sovereignty

Any organization or company should be keeping as many Bitcoin of theirs offline in secure storage that is the best possible defense against hackers of their platforms. The rest of the man power should focus on making their platform secure and prevent the hack in the first place but if it does happen at least their coins will be safe.

Hackers takes time to carry out their evil assignment. This could be taking a very long time for them to trace, track and strike, just that when they strike, they barely miss. At the point of storing assets on the exchange is not really the best, but when these coins stored in the exchange are for trading, then it's not a bad idea, cause you have you major holdings/assets on a mobile wallet with you in full control of your Phrase, password, your transaction password etc depending on the wallet in use.
Because of the high volatility and increase in the price of crypto assets, hackers are working tooth and nail to break through the security system of any exchange out there and big companies, making ransom to be in Bitcoin because it appreciates in price over time.

Same as we always should have. By taking responsibility for our own security. More than ever now, with all kinds of interconnected apps. If your password is weak, change it. If you're sharing a device and connection, closewall it. Especially with Bitcoin/crypto, if you're not the only one with access, sweep funds to a clean device, clean wallet, where you're the sole person able to control it.

Hacks shouldn't serve as a validator for these practices. Merely reminders of how vulnerable we are if we trust our security to someone else.

Retail investors are weakest participants in the market and they are main targets of fud.

Bitcoin Obituaries is a good source to see how Bitcoin is attacked with FUD. If you have a few years in the market, you will see when the market need to be corrected, many news about hack will be announced and spread around social media.

Not your keys, not your coins. If retail investors store their Bitcoin in a non custodial wallet, back up private key, and encrypt the wallet with strong password, how hackers can touch their Bitcoin?

[GUIDE] How to Create a Strong/Secure Password

I was talking about rather small amounts and if your aim is to keep trading every now and then, leaving your crypto on a very reputable, licensed exchange can be an option because otherwise the fees alone for transferring crypto back and forth will most likely destroy any profits you make from trading. I would say it is close to impossible to hack Binance such that they go broke. They will have tons of security measures in place and if you hack them successfully, their system is probably set up in a way such that the hack is not financially fatal.

I don’t see a direct link between the questions posed by the OP and what happened to the companies that fell victim to ransomware. Every serious company knows that it is exposed to such an attack, and the best prevention is to backup the entire system regularly, and keep sensitive data offline. Also, employees should be educated not to open any suspicious e-mails and not to click on links. If that were the case, ransomware attacks would become quite unsuccessful and might even disappear altogether.

For ordinary users, such an attack should not jeopardize their crypto assets if they have a backup stored in a safe place. Imagine a situation where someone doesn't have a backup or they are on a computer that has been hacked with ransomware, and they are asked to pay a ransom in crypto - some may only then realize their stupidity.

Hackers is everywhere and if you're really aware in such issue then it's your consideration how to prevent it every time and as the matter of fact it veey common when it comes crypto investment , especially if you used to invest money in different projects because there's no way you can't encounter such issues, and you will have that experience only because of some projects that lack of security and of course because of some are frauds from new projects that pretending that they got hacked and will run away. Lmao.
So be advised that always assure everything before making investment, because once you got caught and fell to those hackers and frauds trap, there's no way you can regain your money from it.
