There is literally no limit to the number of copies of "Midnight Memories" that can be digitally created. The reason that those particular 1s and 0s are of value is because (inexplicable) people derive pleasure from listening to them. I see the point in BTC for transactions, but they're too volatile to save with, not widely accepted for anything useful (odd pubs in Hackney notwithstanding), and in order to pay my taxes, mortgage etc I'm always going to have to swap them back to sterling. Of all the billions now in BTC, how many are to be used to send money across the internet, and how many are people hoarding to make a quick buck? Why aren't people just buying them 5 seconds before they need them and selling them 5 seconds after they receive them?
Caveat: As is probably clear from the above post, I know the square root of fuck all about economics, but do find all this interesting as a thought exercise and a way of better understanding currencies. Feel free to correct and castigate.
