Earlier quoted context omitted.
Bitcoin is a failed currency - see the original paper. After around a decade of failing to find demand the big holders started to market it as a commodity but since there’s no inherent value to it unless it’s actively traded it doesn’t really fit the usual meaning of that term.
Oh please do explain why it is failed? The only thing that has evolved over time, that is peoples time preference. There will always be demand for BTC. The software works as it was designed, and grows stronger every year. Gresham’s law might be the key to understanding this.
If you think failure is only synonymous with making money then certainly Bitcoin hasn’t failed, but at the same time it has hardly had much affect on the world outside of being a speculative asset for people to get rich off of.
