To level up, you need merits and activity, and to become Legendary you need 1000 merits and an activity of 775-1030 (chosen at random).
He had the merits, not the activity.
Gawd, i got it wrong (again). I'm not surprised, like most of you aren't too...

EDIT: Maybe
BTC can buy me a reliable brain again in the future. But then i will be old, so i won't need it by then

Don't worry, the fact that you own BTC means that you belong to the top 0.1% of the smartest people on Earth. Your brain is fine.
Hahaha!
You should know that i planned to get into Bitcoin in 2013, but fucked it up because i was so confused and forgetful all the time.
But things improved over time, especially through nutrition and therapy, so i finally made it 2017 (when i had about a tenth of unused money available, compared to 2013).
This is not a complaint, btw. Things are fine the way they are. If i wouldn't have learned to think that way, i wouldn't want to know how i would be today...
