The most interesting thing is that it has been designed in such way, so much better security system than any of competitors like Poloniex which have recently lost billions due their hackings! It was really easy for me just by one click I can deposit my money directly into crypto currency but sometimes you need more time if your fiat comes from many countries around the world - there may be some troubles when getting BTC converted back at once price differs significantly between different exchanges/platforms because they usually don't give 100% conversion rate even after 24 hours since last transaction occurred.. But all problems are solvable especially taking profit out during day trading will help make profits easier.
