So there will be more of a demand for Bitcoin since it's limited as for how many will be around until 2140.
Ghost, all of the cryptocurrencies mentioned have a limited supply. So your statement doesn't really prove that there should be more demand for Bitcoin than any of the other cryptocurrencies.
I'm happy to keep talking about it with you!
As for the case of bitcoin...16.9 million are currently in circulation...and less than 10 million are in circulation. .
I'm confused with your comment here. You say there are 16.9 million [bitcoin] currently in circulation and then say that there are less than 10 million [bitcoin] currently in circulation.
There are 16.9 million bitcoin that have been mined. All of them are in circulation because all of those 16.9 million have been mined. There might be 1 million or so that are lost in wallets, never to be transacted again...but that still means they're in circulation.
