Just did the math.
There are around 917 wallets in YoBit.
From those:
20 are in "Delayed" status. That's around a 2%
573 are "In Mainteinance" status. That's around a 62%
324 are online. That's a around 35%. However this number is even smaller as some of those online wallets are running a "YoBit Fork" (yeah, that's even a thing now) and some others appear to be online but they throw a last time warning, not allowing users to withdraw coins.
More than 50% of wallets disabled on a exchange. It's ridiculous.
Yobit business practice:
Jail your coin --> Coin price dropped to 1 satoshi --> Yobit bought all the coins at 1 satoshi --> Open up the wallet --> price went up to market price --> Yobit sold all your coins at market price and make a ton load of money --> Jail your coin again ... rinse and start over again
the SEC should investigate Yobit for price manipulation and jail all the owners for doing this.
