I tried to draw this graph based on the cyclical performance of the asset. If cycles will repeat timing, as we can see an BTC did an ATH in December 2014, one in December 2018, then the next ATH will be probably in December 2022. A Fib channel helped me to find the likely target, to be realistic, around USD 220k.
ATHs have happened in 2013, 2017. So next is expected in December 2021.
