Binance has a very buggy UI, half the time I don't get notifications for P2p orders, chat doesn't work properly, etc
There's also the problem of customer support, I never get the answers I want nor do I understand half the things that are happening or how to solve them - for example, for ages now, I mostly see "merchant ads" only by default when I use P2P, which is not something I chose! Is it a feature Binance has rolled out to promote merchants? I don't know, it's not consistent (note "mostly")
Another problem that many exchanges face, which at the end of the day, comes more to internal fund management, is liquidity
There are a TON of legal and regulatory issues when it comes to exchanges, each jurisdiction has their own - for example, both Binance and OKX have recently completely excited the Canadian markets due to their new crypto laws, so what exactly do you want to know about when it comes to legal problems?
