Bitcoin is not going to reach $20k again, and if that happens at some point, it wont be during this year just like many people is thinking that it is going to be in here. I have already assumed that.
Unless something fundamental breaks, a return to 20 grand is in the bag. There's a lot more head room left.
The other question is when and I don't think it's going to be this year either. I'm not too sold on next year as well but my predictions have always been useless.
