I'm curious to know why you don't use Binance? I see it as the market leader and has widespread popularity. I've been using it for years and have never had any issues converting my crypto to cash.
Binance is arguably the best exchange in the cryptocurrency market today but it is not the only reputable and worth using platform. I think this depends on each investor's preference as I also rarely use Binance, instead I prefer to use Bybit for my main trading.
I also used KuCoin for a while, but I stopped using it when the negative news started spreading about the platform and its founders.
At that time, Kucoin faced a major challenge when billions of dollars of users were withdrawn from the platform due to news related to the arrest of its founder. However, they handled everything professionally without any complaints from users, they deserve praise.
And you should never store your funds on these exchanges, as they are not wallets, and also avoid sending all your funds in one go..
Centralized exchanges are just places to trade, buy and sell, not places to store assets. Hopefully, OP also knows about the Mt.gox and FTX collapse, and learns from it.
