Brothers,
GPU's Do not Mine Bitcoin, Dash, Litecoin.
You have to do more research about SHA-256 Algorithm and X11 algorithm that are mined by ASIC chips.
GPU's dont mine Bitcoin since 2011.
Your answers are Newbie answers for begginers.
I am out and I suggest everyone to stay away, JUST FOR THE FUCKING SAKE OF ICO'S STAYING MORE REPUTABLE AND HONEST !!!
CANCEL ICO, DO MORE RESEARCH, BUILD SOMETHING FIRST, COME BACK IN 5 MONTH AND, I WILL HELP YOU OUT
THATS ALL FROM ME
GOOD LUCK
