Damn, it's been a while I heard about that exchange, are they still existing? Lol, quite funny how Poloinex exchange fell from top spot, no one can ever predict such, I hope bittrex won't follow such route
they are still existing and just visit mcap site and this one still there. So many problems with it just like my friend can't even take his bitcoin from there even he already done various verification to comply with SEC regulation that already used by polo.
That makes so many people don't wanna use it again. When they have told you if they need your passport and they will be asking more after that.
Not sure why your friend having such a hard time withdrawing from the exchange after dealing with the kyc procedures, Polo once was one of those exchange who Excel and get lots of traders but now after binance dominates this exchange is very quiet.
