i bought 500 BTC in 2011 when the price was $3....
....aaaand sold 465 BTC in 2012 when the price was $6

crazy ! but yeah anyone mostly would do the same as you when see your investment has increased 100% in value . i personally hold 20 bitcoin in mid 2013 when the price around $100 and sell it all six / five months later in the end of the year for $250 . guess how much worth it today

. it's always full of regret when you didn't believe in bitcoin right?
