That chart is just a paste from 2014-2015, I annexed zeros to the numbers and changed 2015 to 2019. Bitcoin works in ~4 year periods all centered around the halvening.
Let's see... it's roughly similar. But it doesn't mean anything, in reality. Bitcoin rarely follows past patterns.

Thanks for graphic ... but I think the mainstream and the past value and dev of bitcoin can invalid poiection on the past charts ... and I think we have small time frame in crypto for take analysis with past data...
