during the period from 2012 to 2016 I went through a difficult period in my life and I forgot that I had bought bitcoin it was since the year 2021 that I remembered everything and I do my better to recover my bitcoins
Don't judge a person without knowing their story first.
You went through a difficult period in your life but so some reason forgot that you have over $6M worth inside your laptop, and just sold it for just maybe around 1,000 dollars to save you out of the bad situation you were in (the motive behind selling a laptop in a flea market is obviously money)... really?
How messed up you must have been?

because there was the death of a member of my family to whom I cared a lot then the breakup of my girlfriend and finally I left my country in 2011 to try to succeed in another country and it was my very first trip abroad was not easy but I survived and I'm still here.
with all these events that followed one another I was in survival mode and I had forgotten this purchase of bitcoin in 2010
