This is very unlikely scenario for Bitcoin in my opinion. But I am still posting it, for those who dont want to buy BTC for 50k or 40k... If we will see this cycle of bitcoin sell off after 2-3 years as it was in history in 2014 and 2018, the area around this curve after 80-85% decline (10-15k USD) would be the best opportunity for buying crypto currencies.
I guess it's not happening. But what if... Worth of sharing :)
