Ken, the fact that you simply won't point your phone at one of these miners mining and record a little video screams that you are just trying to scam people.

It's this simple Ken. You either provide evidence or you remain a scammer.

even if they were giving these out for free, I'd still question if it was worth all the hassle dealing with their BS.
looks like you cannot predict BTC or the difficulty............Oh looks like you were just speculating too......... try using 850 btc maybe its more realistic. its about mine and hold. Marketshare of BTC not ROI
