I still haven't met 11 people that own bitcoin in the last 2 years. Actually, I have not met a single other human face to face that owns bitcoin in 2 years... or that will at least admit to it.....
I gave 1 bitcoin to a friend for him to pay his son's university tuition fees in 17 years time. That is the first person I know who has bitcoin.
I also met a primary school classmates, she also had some bitcoins.
So I know only two people having bitcoin.
