> Nobody has a 1e20x more efficient Bitcoin miner either The miners today are 1e20x more efficient than the original CPU based miners. I mean, maybe not exactly 1e20x, but we saw insanely massive improvements, in only 9 years. > Now, if there’s one weird trick to 1e20x your efficiency, and only one group gets it, all bets are off. Only one group really did get the massive efficiency increases... Bitmain, a Chinese company. They sold machines and even mined with them before shipping them to customers. Are all bets off with Bitcoin today? Nope.
