In this chart, I draw a simple line from 2020 low to predicted December 2021 high where I believe BTC would rise to a minimum 95k (whiteline) and possible all the way to 1mil. The redline is movement towards 200k, yellow 350k and green 1mil. However looking at the current momentum, it seems to play around the yellow line, 350k which is already quite a big target for this bull season. So, assuming BTC would reach 350k area end of this year, it is better to buy when price is below yellow line and sell when price is above it. If it goes below red line I will perceive it as a big sale.
