This is an old thread. It asked a fundamental question that is of critical importance to Nu.
I have some thoughts on one of the possible ways to reliablly and fairly generate income to the Nu Network. The idea is to profit from the spread of buy and sell prices of the dual side liquidity provider operated by custodians, without adding undue burden to the Nu economy.
Analysis
After the initial period there will be many NBT/USD exchanges. Most of them do not have custodians involved. The recycle Nebits already in circulation. The Nu Network cannot practically get revenue from them. They offer competitive exchange rates of which the spread is determined by the market demand. When the market demand for NBT is high, the spread increases. Then people would pay at premium rate to buy NBT. This is the time when the Nu Network should inject new NBT into the market and generate income connected to NTB issuing. When the market demand is low, the spread is low, the Nu Network should not inject new NBT into the market, and does not deserve income connected to NTB issuing.
Execution
Injecting new NBT to the market according to market demand is very simple. It is automatically realized by setting the spread of the trading bots, operated by dual side liqiudity providers, a tad wider than market average. When the commercial third party exchanges can meet the demand, people don’t come to the bots. When Nu economy is expanding and more NBTs are needed, people will come to the trading bots to pay extra to get them. The Nu Network will collect the sell/buy spread, less exchange fee and custodian commisions, as Network revenue.
To simplify things I think setting the spread to +/-1% at the bot is good for a start. Since we are still in the initial period of Nu, we need Nubits to be widely used. We can set the liquid provider such way that there are 50,000 NBT (to be determined) availabe at +/-0.002% spread every day. If the quota runs out, the spread will be 1%. There can be more steps. The parameters can be fine tuned.
Outcome estimate and discussion
This revenue connected to NTB issuing is tied to the market cap of NuBits at >1% (sell ~1%, buy ~1%, multiplied by possibly many buy-sell cycles).
Note that due to the destroyed transaction fee, there is a natural demand to have new NBT created if Nu economy is active. This revenue scales to the size of GDP of Nu economy. If the dividends to the shareholders is only taken from this revenue, the interest of NBT users and that of the Nu shareholders are aligned.
