The exchange in general is not bad, but sometimes there are small tricks. In the last month I participated in two airdrop, which I can not withdraw and they are not traded on Binance. In support answered that the technical work (3 weeks, Carl) and it is under the condition that coins - erc-20 tokens. Attention question: what technical work on the withdrawal of ether token can last 3 weeks! By the way one of the coins hive fork steem, read what negative role binans played in this story. And kinda like binans has a lot of positives, but if it wasn't for their arrogance.
