The funny thing is that they're probably not hacked whatsoever.

They were doing this all on their own which just shows the sheer stupidity of the people in yobit's management as well as their shadiness in general. They're publicly manipulating the markets and being proud of what they do and advertising it.

Essentially, they are acting as a pump & dump group, except they can do insider trading before anyone knows which coin is being pumped. An exchange which itself is the player in the market is simply not something that demonstrates trust to me.
