I would say to look at the past to get enough of an idea of the present and future. With this said, it looks like about 2- 2.5 years. Also crucial will be the next halving event.
Actually, I really don't know either when it will be recover and gets back to its ATH price or the price it was last year. But it will take time to recover , all markets go red/low this year, maybe let us wait for the next halving? or even though just like what I said it will not recover fast but if you are old in crypto you will know that when Q4 starts there will be a chance that we can see green port again.
Heck, even back to $40k-30k before is enough for me, not greedy for the last ATH price. What I fear is there will no recovery to that price for this year, but going down furthermore. The market seem like going sideway too much and just some FUD, FED's bullshit could turn a sideways to red.
