You can certainly continue to mine using your CPU and GPU. When I tried it I earned about 0.02 cents daily.
I would probably be singing a different tune had I been mining BTC since the beginning but I wasn't that farsighted.
However I do believe that F@H has made valuable additions to science at a very basic level. Being able to model the process by which every protein in our body folds, and applying it to specific diseases, gives me hope that one day I will benefit, or my children or grandchildren. Or someone elses’ kids.
At worst I have had a great excuse to buy some new toys through the years ...
I was half kidding.
But charitable come-ons are often a Trojan Horse for abuse of the contribution.
In this case, your computer time, or worse, if the program isn’t an evil virus.
So, the BTC question was partially in jest.
I have a son who did some graduate work in protein folding and who “thought” about buying bitcoin when it was in the one to ten dollar range, but didn’t do it. Too bad... now he has to work for a living.
