This Exchange have good services, let you buy crypto currency by your credit card.
However, it seems have lots of BUG, sometimes may stuck your money.
My ETH can't withdraw and trade, some people have similar experience.
So, be careful.
I hope this problem can solve soon.
Yes, there have been some problems with Ethereum (especially on Android) but should hopefully be solved within the next updates.
