Folding isn't even close to mining, and it's not "an algorithm". Folding is a scientific set of steps used in simulating the literal folding and unfolding of proteins.
In mining, GuyA "competes" against GuyB to be the 1st to arrive at a solution to a cryptography based equation. GuyA and GuyB will always be working on the same thing.
In folding, both GuyA and GuyB will go through the many steps to ensure a scientific experiment works. GuyA and GuyB will not always be working on the same thing.
Comparing folding to mining, and saying they are the same thing, is like comparing a car to a tree and saying they are the same because they both have mass.
Stop denying reality.
