I can’t remember but could be in certain context. The ideal situation in my mind is having thousands and thousands currency changers, big and small, all over the place, buy and sell nubits by the side of thier stash of dollars, euros, pounds, yuans, with their own fund, at the market rate. One can’t even count the buy and sell side liquidity over the world. The number of nubits recycling in daily commerce is so immense that it serves as a deep stablizing liquidity pool. The value of 1 NBT is backed by goods and services it can buy or sell. Any deviation from US$1 is pulled back ultimately by Nu but usually by for-profit commercial financial firms. Sorry for the topic drift.
