There will be 21 000 000 bitcoins.
If 1BTC would be 1 000 000 mln dollars then I ask
is there 21 000 000 * 1 000 000 == 21 000 000 000 000 dollars in the world? (21 trillion dollars)
You don't really need 21T$ for that. 1T$ is enough.
Anyway, dollar-hyperinflation is around the corner. We had hyperinflation of major currencies in the past, and will have it again.
1M$ for BTC might be reached easily this way. Of course this won't make you super-rich :-D
When it will happen? Right when China and other countries stop selling goods and resources to US for fiat paper.
Maybe next year. Maybe 2015.
Hmm, dollar is not only currency you can exchange BTC for.
Even with hyperinflation of dollar, let's think. What is the % of internauts (not even avarage people that use internet occasionaly) that has some bitcoins? 1%? Maybe even no. And now imagine that 100% internauts bought some BTC like every of them has fiat money on internet bank accounts. How many will it increase oBTC value? 10 times, 100, 1000? I don't know but I am sure A LOT couse there is limited about of bitcoin.
