It is another story to warn people about risk of storing their cryptocurrencies in online accounts.
From FTX & their CEO SBF, Three Arrows Capitals, etc. and some recent collapsed banks, we see that we can not trust any company which holds customer funds and how they use those funds. We don't know their activities are good enough to keep their companies and our money safely enough.
Reminder: do not keep your money in online accountsThat's the key part of your whole statement "We shouldn't trust any company that we will hand over our funds to'' because they can do away with our funds when we less expect their greed to take hold of them and gamble with our money.
This is what the organization we hand over our funds to, has been doing for so long without our concept. I believe there are many others like him gambling with the mass's funds. This will serve as an example and warning to them all, that they will be caught one day. Just a matter of time
