I've found that yobit steals more than 50% my CANN coins.
Blokchain explorer shows that wallet deposits more that 65000 CANN
Actual balance - 57,263 CANN
Withdrawals: 8.491 CANN (
but i didn't any withdrawal)
Yobit system shows
Balance:
21.500 CANN with no withdrawals or exchange.
There is no answer from their support

So i think YOBIT steal my coins.
