Yobit seems doesn't care about this coin. They have their payment and that's all. No guarantee.
There is a chance they made confusion with an old coin with similar name (Powerstake ticker: POWER -
PowerCoin ticker: PWR). Payment is made through Yobicode (sort of redeem code), and it's not taken until coin is added. We suggested PowerCoin also to Bleutrade (

Just ask:
Did you paid by yourself, or community give you 0.1 for premium list?
I means, you spent much time sendind airdrops, community regret you with some fund or btc donations?
