i'm not sure whether this current bitcoin price run is a bubble or just the currency becoming more valuable as it gains more attention and recognition from world governments. my guess is that a downward correction is coming soon. either way, though, i'm certain that in the long run, the currency is worth much more than the $600 it trades at now. the model i'm using is BTC as a new form of gold. the current value of all the gold in the world, by my primitive calculation, is around 4 trillion. if all the bitcoins in circulation eventually reach a quarter of that value - which i think is totally realistic, most likely an underestimate, that puts the price per bitcoin at over $100k, a number that already seemed reasonable to me. my guess is it'll be there in less than 10 years. anybody want over / under?
