Nobody knows how long it will take the market to recover (if it ever recovers), it could take 6 months like 5 years. Maybe even if he leaves, we will never see a 20k BTC again (some say that this price is not justified in relation to its utility)
Anyway, I don't think the recovery is coming soon, there are still too many people waiting for it to start up again (there hasn't really been a capitalization phase).
And with the crash at the beginning of the year, investors will take time to regain confidence in the crypto market (unless it has good news about regulations)
