The Seven Characteristics of Money
Characteristics that a good currency must be and call itself sound money.

1. Acceptable (Lightning-Liquid)
2. Divisible (divisible by 8 decimal points, It must be divisible. Money should be relatively easy to separate and recombine without affecting its fundamental characteristics. An extension of this idea is that the item should be 'fungible')
3. Durable (15 years uptime, It must be durable. Money must stand the test of time and the elements. It must not fade, corrode, or change through time)
4. Limited Supply (Finite scarcity only 21 Million)
5. Portable (It must be portable. Money hold a high amount of 'worth' relative to its weight and size)
6. Uniform (Fungible, Being of such nature or kind as to be freely exchangeable or replaceable, in whole or in part, for another of like nature or kind)
7. Stable

Finally, it must have intrinsic value. This value of money should be independent of any other object and contained in the money itself.
