I can't say it is a full form.
It didn't even go back there.
Unlike the 12k-13k mark it lasted for months before it goes back down.
20k lasted for what? Days?
I won't expect too much right now if I were you. You can see in this forum, the situation.
There are more expectations for atcoins rather than bitcoin even if it just went after a halving.
hoping too much can also frustrate us. however, I think if there is a price increase for bitcoin, then it might be bigger than last year's highest price increase. but, I'm still quite doubtful that the price of bitcoin can reach $ 20k. indirectly, the price of bitcoin can reach a new ATH if it reaches this price this year. but honestly, it's very difficult.
