This growing use of “crypto” to mean “crypto currency” is not going to end well for either cryptography or digital currency.

When web logs started to be called blogs, there was a backlash from purists, but it's now become ubiquitous. I even entitled this website as a digital log as my response. Perhaps it's worth considering cryptocurrency to get a rebrand, just like we don't call bills "paper money". What do we propose for this new wave of Bitcoin, Ethereum, and the rest of the altcoins?
As of writing this, there are over 750 of them, and they won't be doing away any time soon. There needs to be a clear differentiator -- money as most people know it today is Fiat.
Fiat money is a currency established as money by government regulation or law.
so what should this new wave of currency be called? I'll propose dmoney. It has a double meaning -- digital money, as well as decentralized money -- which is a common characteristic of most (but not all) what we today called cryptocurrencies.
