Bro your weird, this is free mining, they mentioned it, is not like you are investing a fortune..lol...when some one is offering free service why do people get so dumb, go ahead and but expensive equipment and mine BTC's with Sky-rocket difficulty. I paid $60,000 back in nov, still haven't got my equipment back from Advanced miners..If i had invested those money somewhere else...huhhh I would had easy 500K in my pocket, that was a bigest mistake, we made them rich and they mined with our money and equipment:
BUTERFLY LABS Bigtime loosers liars they owe me 600Ghs device since Thanks giving they wont cancel my order.
COINTERRA Better then all these other idiots, they shipped 2 weeks ago my orders-thank god.
ADVANCED MINERS Paid November- NO call Return, NO emails return, no equipment! im about to sue them soon!
VIRTUAL MINING CORP LATE shipping but they returned my money ASAP.
