I think regardless of whether the year was bloody for bitcoin (Which it is), bitcoin is still deemed to recover due to its cyclical nature for profit. There's a plethora of reasons as to why this is the case but all of it is really pegged on the fact that bitcoin's total circulating supply is slashed midway (we call it the halving) every 4 years or something, which pumps the value of the coin drastically by means of scarcity. The next halving wouldn't happen til 2024 though, so as of now I am not really confident that bitcoin will rally upwards this year, unless something monumental were to happen.
In 2024 there will be the halving as you mentioned, but also there's another event that will happen in 2025 and is not really being discussed too much.
The BIS (Central Bank of Central Banks basically), will allow central banks all around the world from 2025 to have up to 2% of their reserves in Bitcoin. Source:
