Look at the volumes on
www.bitcoinwisdom.com,
www.bitcoincharts.com/charts/bitstampUSD, etc. and you might be able to approximately gauge how many BTC could have been bought/sold at that time. Don't torture yourself too hard - for all you know, you could have ended up losing your whole stash in Gox, sold it when it was crashing back to $2 in 2011, or invested it in some scam or Ponzi scheme. Don't be too hard on yourself!
Very, very true. I also took into consideration the fall of Mt. Gox and the thousands that were affected by that. I could have easily been one of those people. Also, knowing my tendencies as far as my stock trading, I probably would have sold it in the $100 range in early 2013, making the total much less than the amount I keep kicking myself with.
I am indeed aware of the famous pizza trade. I've seen the 'idiot' and 'stupid' comments everywhere but its easy to say that in hindsight. That trade is famous today in alot of ways but mainly for the fact that it validated Bitcoin as a currency.
Thank you all for your insight, all I can do now is look to the future.
