Okay so there's only 21 million bitcoin coins, who cares? They cry about how fiat currency can always be printed but never mention how many other crypto coins exist now.
Even if bitcoin becomes scarce through mass hoarding by people like Saylor, if the rest of the world doesn't care then it doesn't have any demand whether there's only 50 or 21 million out there for the free market.
Also if people wanted to use crypto in the future, and let's say bitcoin is valued at 1 million per coin [haha yeah right] why do we have to use bitcoin when other coins can be bought for much cheaper and serve the same purpose?
