The youngest Bitcoiner I know of is
nahtnam. He should be around 15 years old, seeing that he stated that he was 13 over
here (which was two years ago). The youngest Bitcoiner I personally know is 17 and I'm 20 years old myself (will be 21 next week).
Does he have any intention of bringing back the faucet project which he was working on? Interesting thread as I went through it but somewhere along the lines it seems like his ambition or funding dried up, maybe a bit of both.
