Re: How is Bitcoin not a massive waste of energy?

I mine too, but it's a waste compared to what could've been done instead. The "waste" here is that Folding@Home can't come and say "please please use your GPU power for our projects here". There are ~6 million bitcoins, today with a value of ~15 USD each. That is roughly 100 million USD. With all the computing power invested up until now, that would easily solve Parkinson's.
I expect break even and a new system. It's just to bad I'm not contributing to Folding@Home at the same time ...
