People who still hold their funds in Binance are either ignorant, not aware of the recent events regarding centralized exchanges & lending and earning platforms or they think Binance is too big to fail. If Binance bites the dust they'll be the ones affected and a million other holders of shitcoins, the BTC network will be just fine with or without Binance.
I want to believe that the majority of coins that are held on exchanges are owned by day traders who have little choice but to keep their coins there, because of transaction speed and costs. Because it should be a common wisdom by now that coins held on exchanges are almost as good as gone in the long term.
