I’m a proponent of the Trimetallic Standard. Gold + silver + nickel (coins).
Let me know your vote for the best third cryptocurrency to go with BTC (gold) and LTC (silver). My only two requirements:
- Must be already usable as medium of exchange.
- You must believe that it will keep a different price to BTC and LTC, so it can fulfil different roles in the marketplace (think of how you would spend silver coins versus nickel coins).
