They're not just throwing coins out, but users as well by freezing their funds if they refuse to do their verification (or fail them):
Yes I also think bittrex soon gonna be like coinbase where you need to get verified before making any trade. Bittrex is asking for verification even to those who only trade cryptos and not touch fiat. Crypto based trading should be always anonymous but all centralized trading platform are tied up with some rules and regulation so they will always act weirdly.
We need decentralized exchange platform with full potential.
