Robert Greer says that there are three asset superclasses: 

1. Capital Assets are productive & generate value or cash-flow: equities, bonds, or rentable real estate. 
2. Transformable/Consumable Assets: can be consumed one time, transformed into another asset, and their consumption produces economic yield: energy or commodities. 
3. Store-of-Value Assets are scarce, cannot be consumed, just transferred, and their value persists over time and space: gold, currencies, art, or bitcoin.
