The 2021 BTC double top anomaly is in my opinion a result of the covid crash in 2020. Double tops are rare. This one was the first of its kind for BTC. (gladly correct me if I am wrong)
The double top of BTC on 2021 ended on an almost clean close at the 2.272 fib level. Most of people in the space know what this fib level represents.
The next bull cycle top is shown on the chart, that said IF we bottom at the current levels.
