Grain is one of the original barter commodity moneys used in ancient times, which has some of money's best characteristics, such as fungibility, divisibility, unit of account, portability and always in demand. Grain, despite being barter, has been quite a usable commodity for money. $GRAIN doesn't do much else than being a simple, fun, digital bearer money asset that can be used by anyone. Keep in mind that $GRAIN is basically digital "Monopoly" money, so bears no inherent, monetary value and isn't backed by anything (just like government issued fiat "Monopoly" currency). The Grain DOA's purpose is to promote and encourage the use of $GRAIN, for example, literally as game money. Total supply is 210 billion $GRAIN, which means there is 21 $GRAIN available for every person on the planet once the world population reaches 10 billion people!
