i bought near the top of the june 2011 bubble. it went down so far and anyone thought it was dead, i started to think it was a scam and erased everything and forgot all about it. (i had my btc at a mtgox account that got hacked) and felt sooooo stupid that i burnt almost 3000 dollars. i had to wait more than 1.5 years to break even. now those 100 coins are worth 78 k (stamp).

to pay less than $30,- seems so cheap now, but was so expensive for 1.5 years.

same with $ 1000,-
relax, you did your best investment in life. short term you timing sucked, but long term it makes no big difference.
