The only one thing is for sure is that Bitcoin is increasing year by year that's why i did not use some of my assets for my expenses cause i know that Bitcoin will show more in the next few years, it is worth waiting for if we know that there is worth waiting for.
Not year by year but every after the halving.
If we're going to say that the increase would be year by year, 2018 wasn't so good that by that year, it's a long bear market that has made everyone disappointed that looks down on the market.
@OPs prediction for 2022 is likely but I'm looking forward after the next halving by 2024.
