Do you think Bitcoin will be unlimited in the future?
I have good thought on this: The price might be unlimited one day, but BTC is gonna be 21 million no matter what! That's how it was minted by the owner. What can happen is, there could be a day when you will have to count big stash for few Satoshi's and that's how it can be unlimited asset. Obviously this is perspective of the user, whether they are looking at BTC from the fiat point of view or the bitcoin unlimited point of view.
Bitcoin is not itself unlimited and after the last coin is mined, we will chase the other users bitcoin, trade them store them so that the value will rise. The demand and supply formula will work at it's best by this point.
