I used to think that cryptocurrency was a winner-take-all market. The network effects that the "best" currency would accrue would prevent other currencies from succeeding. Now, I foresee multiple cryptocurrencies succeeding at the same time.
Money is the most liquid good. It’s value comes from it being the most saleable good. All the reasons for why we have 150+ fiat currencies (borders, states, tax laws, debt extinguishing laws, legal tenders, etc.) don’t exist in the digital borderless realm. So why several moneys?
