I do not think there is any pre-halving #Bitcoin rally.

The actual day of the halving is typically a non-event.

Taking a look at all previous halvings shows a lack of correlation.

- A small bounce took place leading up to November 28th, 2012. But the majority of the price action right before was decline

- Price rallied sometime before July 9th, 2016, but declined into the halving

- The May 11th, 2020 halving came in the midst of sideways price action. Before that, price was recovering from the black swan

What happens leading up to the halving is more likely entirely dependent on what is supposed to happen according to the cycles.

The Halving Cycles Theory says that Bitcoin is only centered around the date of the first Halving, November 28th, 2012, not each individual one.
