At this point, if each user wanted to have 1 Bitcoin, will have to pay a certain number of $ or € or Y, whatever. I'm going with $ just because it's the most used around the world.
How many $ do you think that person, the n. 21 millionth, who wants to buy 1 BTC will have to pay to obtain it?
My wild guess is: 160000 $.
A lot more than we thing probably. Always take into account there are way less coins available than 21 million, a ton of them are lost forever, and a lot more aren't even mined yet, so if that threshold is surpassed the price goes higher. I cant honestly give you an exact number. I like the Xapo's CEO prediction: between 500.000 and 1 MM dollars.
Not to forget Satoshi's coins, which I think will never be used.
21 million users is not too outrageous. It is just 2% of facebook's active users.
I would say $10k will be breached when this happens.
I don't know, I think that when we will be heading towards 21 millions users, there will be so much rising in request already that the price will blow up in unpredictable manner.
It will probably also spike up into a bubble and then fall back down to the real value.
And I think Satoshis will much probably be used before 10 years from now.
21Million users is different from 21 million coins in existence. We'll probably hit 21 million users long before the 21 millionth coin is mined (which is expected to happen in over 100 years). Remember that the mining package won't be in single coins at that point, it's possible that the 21 millionth coin is never mined because it would be way to expensive to do so. Perhaps the person that earns that coin is the one who mined it, for nostalgic sake.
I wonder what your price would be in present value dollars (accounting for inflation over the next 120 years)? The value of today's Dollar would only have to inflate 551x for $160,000 when the 21 millionth coin is mined to have the spending power of today's $290.
