Hi,
I'm mining pool operator at unimining.net I was contacted by ma7555. He asked me to block his wallet address because of a problem on NiceHash. As he explained, we blocked his wallet address and restarted stratum to stop existing connections, then the mining was stopped for this wallet address. Unpaid balance was paid afterwards.
Maybe NiceHash is having some problems and that they'll communicate soon about it. I don't think that NiceHash is a scam. I don't like NiceHash, I think that they are expansive but I think that they are honest and that they will reimburse people or maybe find a solution or explanation.
Best Regards,

Same for me too. I was using your pool. XVG address of DGUKSrVnX4iDPiKwrXzULXXUFno8oN8W42, but I cannot mine using nicehash for while.
