Due to huge crypto exchange FTX brankcupcy . what is your lost amount?
my one is 120$ and i got the a new message that "Not your keys , Not your crypto"
This is one of the song that many experienced investors used to tell people being careful about exchanges. Since you don't have access to the private keys then it can never be your coins. Even with these kind of senerio that had been happening for long now, some people still keep all their coins on exchanges to hold their and most time, they even stake it and expect big APY which can be profitable but still very risky. We should learn from other people's mistake and keep our coin in our wallet to avoid painful story like this.
You are right about this, and people who did not do what you preach unfortunately suffered great losses. There is no point in keeping your money in the stock market when you are not trading. Why are you taking risks? If you bought a coin and something like FTT happens to you, it's probably too late. These and similar problems are unavoidable in the market. At least for now.
