I heard it back in 2011 where in there was a huge hype of mining Bitcoin using GPU's and there were numerous facebook groups where they posted they rigs and also had many tutorials for other to follow or even customize their rigs in order to work better.
I heard bitcoin in my classmates they really seems to be happy when they arr talking about bitcoin before and I seems not to care believing before that bitcoin is a scam, illegal or whatever I might be wasting my time if Im going to try it and then I saw them exchanging money for their parts in bounties my bad cause I immediately just this kind of valuable system instead of trying, now I am slowly learning and earning here as well.
