Anybody who willingly uses this site is asking to have their coins stolen. Even Zcash which is fairly hot right now is messed up there. I have lost coins here 3 times. 2 of those times were coins that were not being traded elsewhere. So I got an addy from yobit and sent coins. Never saw the coins again and all you get from a yobit support ticket is an argument with a robot.
These are thieves plain and simple. Yet people still support them or is it that they only service you after you pay a blackmail fee?
Zcash wallet is very unstable. Now it's online.
