even bitfinex is doing these "source of funds" checks even as they hide out in the BVI. the crypto wild west is basically dead. if the seychelles exchanges (bitmex, binance, poloniex) are ever brought into line, it'll be completely dead.
that might be a matter of jurisdiction.
they've been doing the mugshot thing for at least a year now on bittrex.com (USA). the OP of this thread is a global (non-USA) customer.
