Firstly, not all bitcoin operations as you put them, go under. It seems that every time an exchange has a security problem, the media jumps all over it and that is what people will remember. You rarely here about the success stories. The media is much less interested in those. However, if anyone is interested in a success story, then perhaps they should pay attention to Exmo. Since 2013, Exmo has been able to stay ahead of those devious individuals, whose sole purpose is to hack bitcoin sites. We have no intention of ever succumbing to such sabotage. 




Thank you for your interest in Exmo!
