In order for something to function as money (currency) within a society, it must meet the following requirements:

  1. Cannot be easily counterfeited.
  2. Portable
  3. Non-perishable
  4. A store of value
  5. A unit of measure

That’s all the ones I can remember off the top of my head, I’ve probably forgotten something.

Bitcoin and all the other cryptocurrenices meet the first 3 requirements but fail to meet the last 2.

 

Just because cyrptocurrencies call themselves “currencies”, doesn’t mean that are. I realize

there is now a hell of a lot of emotion tied up in these assets so this is my 1st and last word on

the topic. My point is, in terms of economics, they ain’t currencies.

 

Edit: Here’s that Charles guy from ZH take on it, who thinks Bitcoin is money:

My key point is that for something to function *as money* its value cannot change wildly.

In the real world, when the value of money changes wildly that is called hyperinflation, e.g.

Weimar Germany, which leads people to avoid using the currency altogether because it

no longer fulfills the last 2 requirements.
