I was there when it hit the ATH in the $40k price range and I sold some coins.... but I kept on to some more coins and the price dropped to $3000.
Are you saying that you sold some coins at 40,000 dollars and after that the price dropped to 3000 dollars? Am I getting you correctly?
If so, I don't remember the price ever dropping from $40,000 to $3,000.
Bitcoin dropped to around 3000 dollars in December 2018 and the ATH was around 19,800 dollars in that time. Bitcoin reached 40,000 in January 2021 and reached 60,000 dollars in March 2021.
