Did some bitcoin calculation on leapyears.
And found a nice price calculation on bitcoin
On the first day of a leap year we look at the price.
In the middle of a 4 year period we reach a new ATH.
Every time we use the price on the leap year.
This price x100%
The New ath is the December month from the 2nd year
Every 4 years we have a leap year. and the price pumps 100% from the range where the leap cycles starts
2008-2011
2012-2015 100% 2013 new ath
2016-2019 100% 2017 new ath
2020-2023 100% 2021 new ath
