Well the fees are obviously high - but you get other benefits from trading @ binance:

1. Withdraws are quite fast (compared to Bittrex at least)
2. BNB trading fees 50% lower than regular TX fees (ok - you need to own BNB)
3. Almost weekly trading competitions.
4. Support to almost all forks.

For me this four bullets make the difference. And @ the moment - if you didn´t already register on another exchange - well, now it could take some time to do so!

Cheers
