How did you manage to twist a truism into a fallacy? You shouldn’t make these claims, because if anything arguably you used a hasty generalization or fallacy of composition.

Not all cryptocurrencies are bitcoin nor do they work the same at all. For example, many don’t even use “mining”, which is the source of bitcoin’s outlandish energy waste. I really have no interest in discussing cryptocurrencies, but at least don’t do so in defiance of common sense.
