Sometimes I also think why investors only use the FTX exchange to store their investment funds, even though there are many other exchanges that are also better than FTX, although it is highly not recommended to keep funds in the exchange for too long. Because everyone needs to have a special wallet if they want to store funds safely for the long term. So on the other hand, investors are actually wrong if they only save funds on the FTX exchange, even though the basic core of the problem lies within FTX.
FTX is also one of the biggest and most reputable exchanges apart from several other exchanges. Investors who keep their funds in the exchange know what the risks are, but because of the good reputation of the exchange and good security, maybe that's the reason why they entrust their funds to third parties. Just like most people who believe in binance and coinbase right now, they know the risks.
Traders and investors are fundamentally different. Traders tend to keep funds on the exchange regardless of how much they have, while investors tend to have funds in their wallets. Some traders have millions of dollars in their trading accounts, but I don't think they are investors although some investors also keep their funds in exchange in the long term.
FTX also used to be under Binance and aligned as a leading exchange you can say FTX gives customers convenience with free withdrawals that's what I feel while using FTX when they often make small withdrawals and of course as they trust FTX because it has become big it's just unexpected due to bankruptcy experienced by them so that it becomes a risk that must be known.
Traders, of course, have daily activities on the exchange, so they store their assets on the exchange, while it's different from investors and they know how to store assets in their own wallet, it's just that an unexpected error from FTX makes them dumbfounded.
