I am a nasty cyber-punk who learned about bitcoin back in 2011 and got my first bitcoins at that time, I just mined them on my work computer, while doing my own business, which did not bother me much, by those standards, my computer was quite powerful.
I didn't have many bitcoins, only around 30-40, I don't remember exactly, at that time it was only a few dollars (February)
So you mined a block and then either gave away, traded, or sold 10-20 bitcoins in February 2011?

Going by his posts since this one, this guy was looking to establish some "cred" via merits before running some currency exchange scams.
The story can't be verified and doesn't really make much of a difference since the OP is not selling anything.
This has since
changed.
Not only do I think OP was here farming merits to help him run a scam, I think I know who he was in past incarnations as well. But this can all be disproved with pictures of a hard drive turned into a key holder. Just take 2 pictures of it next to a piece of paper with the day's date, and I'll apologize, and even give you the 3 last merits you need to make Member status.
