Summer 2012. Diablo 3. I bought in game gold with bitcoin @ $3/btc - Spent 90 coins for 500 million in game gold.
IGG = 35 cents / million now.
I lose.

The worst decision that I made is when I didn't buy bitcoins when the price of the bitcoin is still cheap. I still remember that he price of the bitcoin is only $400 per each. I am now a millionaire if I buy bitcoin back in 2013.
