I need an even lower level.
Seriously, I know this stuff is out there but is it only real because people do mathematical equations to verify it. Sounds like astronomy.
Maybe bitcoin is in it's infancy but I prefer something that is based upon something tangible.
"We know exactly how many bitcoins there are in existence today (12,446,725) and how many there will eventually be in total: when the 21 millionth bitcoin is minted, the plates automatically self-destruct. (This is a metaphor, of course."
Imagine that the creators of bitcoin ( digital currency ) were a printing press like the Treasury Department. Originally (supposedly) U S currency was backed by gold. That finite quantity ceased long ago when we went off the Gold Standard. Now Congress authorizes debt and Federal Reserve Notes are printed ( ad infinatum ).
Bitcoins are crypto currency. I would imagine that once the 21 millionth bitcoin is mined they will split, just like "stock".
