One Gram

OneGram uses blockchain technology to create a new kind of cryptocurrency, where each coin is backed by one gram of gold at launch. Historically gold is more resilient, and holds its worth better than any fiat money, particularly in times of economic instability. No currency can guarantee absolute stability, but OneGram limits your exposure to the downside risk.
Because the base price of OneGram is always at least equal to the spot price of gold, OneGram has a floor price.
