Bitcoin has been around since 2009 and it's just in it's infant stage now... The currency used in Second Life only had value because of the network of people using it, once that disappeared the value declined.
Bitcoin is not fake money generated from thin air... Everyone knows only 21 000 000 coins will be generated and that gives it value. If nobody wants Bitcoins, it's value will decline... the same goes for any other
currency, like Yuan / Zim Dollars... < The only difference... The Central banks manipulate this, by printing more of less of a currency to retain it's value >
