In 2022, when some Chinese banks decided to freeze depositors accounts for shady reasons and debitors planned to protest the issue, authorities used Covid codes to block them from accessing the banks. That also does not seem stable to me.
That's quite different, and virtually no one lost their money in that it was simply stolen by the owners of an accredited brokerage/exchange/bank, like what happened to FTX. And FTX wasn't simply gambling with other's money, they were defrauding their customers (to whom they claimed they are holding all of their money in custody) and also directly embezzling this money for their own gain (houses, publicity, illegal political investments).
That's not the point. Everyone knows that crypto is full of scams and everyone tells you that you are supposed to hold your own keys instead of leaving coins on an exchange. Almost nobody tells you that keeping coins on an exchange is good practice.
The average person has no idea what you’re talking about when you say you have to hold your own keys, and would be absolutely screwed if/when they lost them.
Getting locked out of your own crypto wallet is a much more significant threat than government seizure for 99% of the global population.
And yet, there are many times over more people using exchanges than holding their own wallets. I don't really care about crypto-in-principle, when crypto-in-practice is anything but safe.
The government has the ultimate say!, what happens if they order all ISP's to stop traffic to BTC trading sites (or even shutdown internet if it wills)
Solutions like the great firewall exists that constantly "learn" and will lock you out immaterial if the government decides so.So the argument that BTC / Crypto will take me to the moon (SafeMoon) is wishful thinking
If your government decides to kill the internet, I think that's a very good reason to try to emigrate. The fact that China is doing it, may make them look powerful, but it also makes them look tyrannical.
