Although it is difficult to say for certain when Bitcoin will go down before the halving or after the halving. But we usually see a downfall in the market before the halving. In the data you mentioned we can see that the 2020 halving has gone to the highest down which is -62.5%. But compared to the previous downfalls of all the other halving events, this time i.e. before the 2024 halving, we see the least downfall, from which we hope that this time we are going to see this extraordinary game of Bitcoin.
