This is a simple chart that explains my prediction on BTCUSD for 2021 to be around 17.5x to 20x.
21 weak EMA (red line) is going to be left behind, just like in 2017, and 2013.
A good strategy should be to buy now, close a significant ammount at around 17x profit or around october, and then start closing slowly as the year ends and further analysis can be made....
