That is true and we do not know what could be the high price for 2021 and what if it just get dumped badly, though I do not think it may take that long time like from 2107 to 2020 it took to reach ATH again, but it could be much sooner than that due to various institution getting involved, bitcoin is being also being bought by people who ignored in start and said to be bubble etc.
Do you think that the 2017 rally is made possible just by individual investors, these institutional investors who are pumping money into the market made their investment during those period as well and they booked their profit and so is the reason we saw a huge correction after touching its all time high valuation and we should expect the same as these investors will book their profit.
