Not FUD, rational analysis #BTC buy-in price

This round of bull market:
Bitcoin highest 126119 USD, lowest 65000 USD, drop of 48%
Based on the drop estimates of the previous four bull markets, if this drop is around 70%, then the best buy-in price for BTC is about 40000 USD.

40000 USD BTC seems despairing but is the best time to enter and buy.

I personally think it is very reasonable. What does everyone think?
