What do you mean Binance doesn't accept any user? As far as I know, Binance is open to anyone, in fact, this exchange is what I am currently using now and it doesn't fail my expectations. For me, this is one of the best exchanges I've been used, I can able to use it without submitting any KYC requirement as long as you have your funds don't reach 2BTC Binance provide better security they had the reputation which is I mainly looking for and it even have the highest volume in over all exchanges, thereby my bias exchanges is Binance.
