  • It started as just a digital property, like online beanie babies.
  • Soon we found that monetarily worthwhile, so began trading it for fiat. (Securitized)

  • And one day, when most everyone is spending it, we'll all price our good in it, using it as a Unit of Account.
Clearly we are working on Method of Exchange still, and as Layer2 payment rails are perfected we'll get the rest of the world jumping on board easily. Right now it's not so easy. I'd say another 10 years before it's an actual Unit of Account anywhere. Maybe 20 years before it's a Unit of Account (and the world's reserve currency) everywhere.
