Well I admit.
When Bitcoin tanked down to 5000, 4000 and 3000 I sold about 20% of my Coins :-/
This was obviously a mistake ;-)
At least I still have ~80%

Weve all made mistakes, theres no point worrying about the past & things you cant change.
I wish Id bought a fuck tonne more at 3 figures.
Whats important though is that you have a stash now.
Prepare to be one of the new wealthy elite my friend. 2021/22 - watch this space.
