Everything can happen, the most current information possible many people say is impossible bitcoin used almost people in 2022, same as current price, a year ago no one thought bitcoin price could reach $ 17,000.
It can really happen in 2022 because for now 2017 some of us use bitcoin and the users will be more when they knoe already the bitcoin and the profit they get on it.
Yes agree, all things can happen and often unexpected, maybe now many pessimistic that bitcoin will be used almost people in 2022, but 4 years time is still long and enough to make everything happen.
