I first heard about Bitcoin in early 2011 when two friends were debating about it. After long debate...one joked that he owns the moon and can sell it to the other guy (one defending Bitcoin) for a cheap price of 5k. We all laughed about it.
Later, I was watching a TV show and the episode was about a lawyer (Good Wife) defending someone involved with Bitcoins. I only watched about 10 minutes of the show and quickly got bored and then went to play indoor soccer at a nearby stadium with the kids that were bored.
I do remember checking the price of Bitcoin and it was around $3.45 and I then had this thought...maybe I should do some research into this.
I lost interested in 2012 after I read a news story about something big being "hacked" and then I saw some negative posts about bitcoins after the hack. I think it was around $5.00 at that time.
