Your statistics shows that bitcoin only grows and that's not a correct indicator to only look at price stamp of certain months because there was a lot of changes in prices, that includes prices lower than those indicators and higher ones. We had $6579 in 2018 this time but at the same time we don't have to forget that 2017 year played a huge role in it, the rise up to 20K USD. But we had moments like price between 3-4K USD. Also, more than 1 year ago bitcoin hit 14K USD again but still didn't reach to that amount again.
Don't trying to prove anything from my post though, but I guess the month of October became memorable because of 2017 blast, as we know October that year is really the start of bull run of the most incredible time of bitcoin so far. And I agree there are factors that affected the price, it's too many to mention. It's just that October is memorable.
I don't like only looking at numbers because there is history behind every number and there were certain moments that caused those numbers. What about to write price stamps of bitcoin for each month of certain years? Will it look as beautiful and hopeful as October?
Well noticeably, price in month of October every year is good, maybe the start line of the a good run.
