Looking over the uncontextualized data, price has a good behaviour on only one out of the past four Decembers, being December 2020 structural the path to the subsequent 2021 ATH:
Neverthless, I get the feeling that looking over the past monthly aggregate data does not really point to future trends for a given month, and that were much more prone to sway, in price in terms, to the tune of the large fundamentals that occur, which are mostly unpredictable.
I love this image, I love the fact that none of the months in general look like a heavy green month aside from maybe February and October. The reality that we can learn from this image is this, you could have one month of 172% or something, and then 6 months of 5-10% drops, and that should tell you how bitcoin goes up. Maybe for the next 12 months we are going to have 5% drop each month until last month where we have 400% increase?
We do not know if that will be the case but this image shows it's also not impossible. Bitcoin usually slowly drops more and more and more, and then one day goes up straight like an arrow, we need to be ready for that and if we are not, we will always be too late to it.
