I remember when I first looked at Bitcoin, it was around $1 but I didn't buy any because it seemed too risky :) Then when it was $100, I bid for a Bitcoin miner on ebay and was outbid. I should of tried again but I just gave up. Then I ended up finally buying some when it was almost $5k. I don't feel bad about it now though. There's nothing I can do to change the past and it's a good lesson for the future. Had I bought at $1 or mined at $100, I would probably of sold too early and that would be worse.
