a week's increase is around 10 percent. Bitcoin saw $ 15k comfortably. So, I see the potential that the old ath could exceed $ 20k, this is not investment advice. It's just my guess opinion.
I may not agree with what you say but it could be that my analysis is wrong and you are right. seeing the movement of bitcoin in the past few months bitoin has always been rapidly increasing and decreasing, so no need to be surprised that bitcoin will be able to go down again but eventually at the end of the year will be in the range of $ 15K.
