If you are talking about binance exchange, then they have an office in a hung Kong and as a centralized cryptocurrency exchange under the legislation, it can be sued to court by anybody or users who use the exchange if thoroughly you have evidence to back your case.
I don’t think anyone really knows where their headquarters is, because I have seen people say that they are based in Malta as well, apart from those saying that they are in Hong Kong. And one thing I noticed is that Binance don’t give out information about that, it’s been a secret. Maybe if the op or whoever wants to sue them, they can start with any of those and start the case.
But I am yet to understand what the problem is with op and why he’s calling Binance a scam exchange, because that’s the exchange I have been using for years now without having any issues at all. Same thing with Coinbase, and I have seen people say that Coinbase is a scam exchange too. The last time Binance got hacked the users were not affected and the exchange took the loss. So it might be good if op takes time and explain what he’s going through and whether he has tried contacting support from Binance.
