Had an opportunity to purchase 1,500 Bitcoins in 2011 for $3 each.
I listened to the Wall Street Journal, and told my co worker no thanks. He left my job in 2013. Made enough money to retire.
I finally got in a little over 3 years ago. Overall I am up almost 400%.
Like most Ponzi schemes early in and early out makes the real money. The rest are holding vapor-currency that may or may not be able to convert to something of fiat value.
