The exchanges you mentioned have a way of boycotting regulation which is why they mostly have issues...Binance have issues with many European countries including UK, Canada, Australia, Japan and many more..... When it comes to centralized exchanges, there are only a few that are regulatory compliant like Bitget and cryptocom
TBF, most successful exchanges starts as an off-shore company which is a typical initial setup to stay at the gray lines. Also pretty much one of the reasons why a lot of them were able to do a no-mandatory KYC policy (for purely crypto transactions) at first.
I never cared much about bitget TBH but I must say, you post about them a lot
Times have changed mate, crypto regulations and compliance is a thing and when an exchange openly bycot regulations despite restrictions, then it's brings questions about their legitimacy imo.... About the other matter, maybe he uses the platform and just sharing his experience/tips which is normal buddy.
