I just drew the simple lines that would reflect a normal growth without any hype or bull run. Without 2021-2022 bull run, normal growth of the total crypto market cap should be somewhere between $750 billions and $450 billions. And this could be the bottom of the total crypto market cap.
I will start to buy in BTC, ETH or alt coins when the total market cap is around $600-$650 billions. This is the only "TA" that I do and I believe.
