I will guess everyone who makes a comment here will say "binance".
it is a fact and binance population is increasing, as well as bnb coins, everyone is hunting for it to get an IEO opportunity.
Because Binance is simply an exchange platform that makes users very trusting and support very well, almost very few people complain about their exchanges. CEO CZ also a very active person interacting with the community,they also have a separate fund to compensate investors in case they get lost by hackers.
So for me binance is the exchange I chose.
