That will be in Russia. You're not going to tell me that Binance or Coinbase are not legal are you?
As far as I remember in the other thread what you are describing already happened. A Russian exchange of which it is difficult to find data or any license, demanding KYC, or else they block coins. At the very least it seems morally questionable, and would not be legal in the EU or USA.
Why are you comparing Binance with exchangers from Bestchange? Binance is a legit registered company. Please show me legal info from at least one of the exchangers. You won't find it on their websites. So it's completely different. They aren't legally registered companies, they work anonymously. So they don't have authority to ask for KYC. And Binance has authority to do this. I don't like what Binance is doing and I think it's inappropriate but they have authority. And what exchangers are doing is illegal in Russia too, not only in the EU and USA.
