Custodians are compensated with NSR in a tllp. Why would you just hold btc when you could hold btc and get paid NSR for doing it? In the beginning, liquidity compensation may be large, but definitely far less than the 100%/year or whatever absurd amount we’re paying for nbt/btc buy side liquidity now. There is no hedging risk, and as NuBTC becomes more accepted the compensation will go down. Also, they always win on the custodial spread by putting up a buy at .995 and a sell at 1.005 (or whatever).
Also, if NSR is unspendable, if you want some shares and you aren’t a programmer or a liquidity provider you have to buy NuBTC (or nbt or whatever) and burn it.
Edit: in this model we don’t even really need park rates as they are kind of redundant. Mint rates and tllp rates are enough.
The changes required to accomplish this are large. The first steps are nbt/fiat pools and burn mechanisms, which do seem to be on the forefront of the collective mind. It’s important to be aware that multiple burn mechanisms can in theory take place at the same time, but we want to be careful about how we distribute a) our developers time, and b) our block space. This is not the only way that Nu will become profitable (tx fees, loans) or adopted (payment processors, marketing, stable exchanges, gambling websites) but it is a useful core concept of peg maintenance, in my opinion.
