I have no doubt that Bitcoin specialists are very smart people but they keep advocating a dumb-simple brute force algorithm to secure their money even after people state the obvious that it wastes vast amounts of electricity for very little benefit and a great deal of harm to the majority of humanity. Can they secure their Bitcoin with a smarter algorithm? Apparently not, because they are too busy being greedy and denying the truth.
