When people trade their respective government legal tender for a cryptocurrency and engage in trade of some form with said cryptocurrency a bubble? Is the current total outstanding global debt a bubble from where it was 20 years ago? Are institutional purchase of negative yielding bonds a bubble? Are global central bank purchases of global stocks a bubble? From where I sit, the bickering over the price and how justifiable it is/isnt where, is ignoring the larger societal changes taking place. All I know that, in Indonesia, I can have a website with a monero miner on it, and use the proceeds to pay for electricity, food and shelter directly. This wasn't happening 5 years ago. And this says nothing about tax enforcement, law, and even warfare that won't go untouched by this. For the non marginal users of crytocurrency, typical speculation rules with financial instruments still apply, but for those who can do what they couldn't before… yeah, this is just the beginning.
