I think that was on 2018 and bored in a way that it was a bear market and prolly he lost hope by that time. A mistake that can no longer be corrected but can still recover somehow through accumulation.
2018 and especially 2019 were the period when people lost hope on Bitcoin as it was an extended bull run and altcoin bloodbath, Bitcoin was under $5k in 2019, I remember so many people selling it off and whales silently buying it and accumulating it. Even now people made same mistakes until recently they sold Bitcoin for under $20k only to regret it now, I think I have learned a good lesson I have started accumulating Bitcoins through DCA and don't withdraw any funds unless it's for emergency purpose and people should learn from previous mistake instead of falling for fuds and panic selling or selling for huge loss.
