Weak. Back when I mined, we were real men -- even the women -- and we had balls of steel. A little variance? Pffft.
Unfortunately, I am getting to the party a little late. I wish I would've joined sooner and now have more than $5000 invested. It's the only way to make it sustainable - a little profit.
Why did you stop mining?
Electricity costs made mining unprofitable. [edit: in my location, that is -- still plenty of places where electricity costs are ok for mining]
