I appreciate the direction!
Compared with my modPuddle operation at hitBTC ($1,500 liquidity for 225 NBT per 30 days) it seems to be a bit expensive.
Of course that depends on the trading volume.
If you really have to refill every day, the 150 NBT is well-earned.
The SAF is high enough to provide some gain with the traded funds.
What about applying for 1,000 NBT from Nu funds, which get refilled once per week (if necessary), you withdraw BTC proceeds once per week and offer that service (none of your funds at risk) for 50 NBT per 30 days?
