Bitcoin to a million is possible It's a deflationary currency, so it will almost never make sense to use them for regular real-world transactions. Supporters will tell you there's 3 advantages to bitcoins:
Making transactions you don't want linked to you/your name
Transferring money without paying a 2%-3% fee to go through wires or Western Union or whatever
Storing money outside of the big banks
As long as those advantages hold for Bitcoin, and as long as we know there's a set limit to the number of bitcoins and there will never be an increase in the max number of bitcoins (you can still currently mine them but 99% of Bitcoins will be mined by 2030), then there will always be a demand for the limited number of bitcoins for the 3 uses above, especially as adoption increases. A basic macroeconomic principle is that if demand increases and supply doesn't, then prices go up. So any bitcoins you use to buy a car or whatever, those bitcoins will be worth more a year from the date of the purchase, on average .
