History always repeats itself but you never know when it does. The Bitcoin made all time high record back in 2017, the track record of BTC is that every three years it breaks it ATH record.
The analysts have mentioned about the bitcoin price after the halving, and yes it is possible that a bull run and hit the 20k ATH is possible. almost the same cycle as last 2017. Also I hope Altcoin will move up together. Im sure, many trader prefer to waiting for Alt seasson.
