What if some of their users will use some VPN applications to access the Bittrex International exchange?
Provided the users haven't completed any sort of KYC, and are careful to properly hide their true IP (there are many ways a browser will leak your real IP even if you are using a VPN), then Bittrex won't know. It will be fairly obvious, though, if accounts which have logged in from Tunisian (for example) for the last several years all of sudden switch to an American or European IP.
Members often question if bitcoin can ever be destroyed, and I have always said it can't, but what happens if and when exchanges no longer exist? Don't think that will ever happen either, but one by one they seem to be going down.
Honestly, I look forward to the day that these centralized exchanges no longer exist. I have never used a centralized exchange to turn fiat in to bitcoin and have never completed KYC, and I get by just fine. It's getting easier and easier as time goes on to not have to use one, with the growth of the peer-to-peer scene and DEXs such as BISQ. The entire point of bitcoin was to move away from using third parties. Trusting these unethical, shady, and often borderline scammy centralized exchange with your data, your documents, your coins, your money, seems backwards to me.
It is idiotic to not help these people out, you have to be caring about how much money you will make in revenue more than you care about helping people out
Welcome to centralized exchanges. Every single one is a business first and foremost, and they care much much more about their own profits than they do about their users.
