Guess what? I wasn't interested in his offer as I never heard about bitcoin before that and thought I have no use with it.
I came to know about bitcoin in December 2013 when the price was at $1000USD per BTC.
What I did with that $20? Lost to a scam HYIP.
If only I accepted his offer, I'd be a millionaire. That shit still makes me sad everytime I remember.
Luck did knocked my door, but I was dumb enough to ignore
How about you guys? Ever had an experience like me?
UPDATE: Even if I have bought it from him, I'd sell it to someone even each BTC was $10 worth. I'm so impatient you know xD
