GM are covertly scamming while masquerading as legitimate businessmen. Last year, they took US$1750 of my money for 100MH of Scrypt mining, quickly reduced payouts by over 40% within 60 days, forced the conversion of all accounts to SHA at an insulting 1GH per 1MH (20x less than going rate), further reduced payouts every month by at least 10% even when the BTC value was rising, and as of three days ago, stopped paying... Now my account investment, which is still $1400+ in the red, is dead or "cancelled" as they call it.
They are no better than GAW in my opinion. They can continue to promote themselves and their broken business model all they want. Those of us who paid for their start in 2014 know better and the more people who know the truth, the better.
