What will happen to Bitcoins, or more specific, to the price of a Bitcoin, once all 21 million are created?
(1) At the moment we all talk about miners, GPUs, ASCIS, bulletin boards are filled with discussions. But once no new BTC are mined, will the price drop to 0? Because no one cares about BTC any more?
(2) BTC is meant to be a currency, right? But can I buy beer with it? Or a notebook? Book a flight? It seems all people do at the moment is trade it on MtGox, etc. - but they don't buy goods. No?
I think the fact that there is a limited supply will actually increase the price of BTC over time. Think about it, everything rare in the world is expensive : Gold, Diamonds etc - because they are hard to mine.
Fiat Currencies are getting devalued all the time - because they keep printing more! Thus your $'s are losing value! But BTC - there is a fixed and dwindling amount ... this should cause the price to increase.
