Is there a btc address they own which is mining with 1PH?
out of curiosity, wouldn't it be interesting to know where the
BTC PBmining is paying weekly have been minted ?
( or is that also hidden by their mixing-service ? )
Some time ago, probably in this thread it was pointed out they were paying for the same wallet people's payments for GH/s when into. However that wouldn't mean they aren't mining. PBMining has simply refused to provide any proof that they are actually mining. They have a nonsense cover story about how it would be a security risk to do so.
