NuShares are units held by individuals who wish to help support and maintain the Nu network. Owning NuShares is not required to use NuBits. Instead, NuShares are intended to be a source of network equity for developers, entrepreneurs, and speculators. NuShareholders can receive network revenues in the form of Peercoin dividends paid out by a custodian.
NuShareholders can cast votes for actions that positively affect the Nu network. These actions help adjust the supply and demand for NuBits so that they will always remain at a long-term $1.00 US value.
