If you've been in crypto for a while you can see we are at the beginning of the next Bitcoin bubble right now. It's now a matter of how much bigger this bubble will be from the last one. We could hit $20,000 this year, even within the next month or so, depending on what happens. So $20,000 really is the very beginning of the run up.
Will it go to $50,000? $100,000? No one is sure but both are possible between now and 2021.
I completely agree with you although I foresee another slump down to somewhere around the 4k range before it starts the parabolic rise smashing through the ATH like it was nothing.
200k by 2022 is what I would put my money on if I had to.
