It’s very expensive for Nu to provide traders with this feature. I hope NBT get used for payments soon as only being a hedging instrument will bleed Nu out over time.
The problems are not completely gone, but have been traded for lesser problems. No Nu funds are at stake of exchanges defaulting, but funds of people providing liquidity are at stake.
They need to be compensated for exchange default risk as well as the volatility risk (as long as non NBT/USD pairs are directly supported by Nu).
One might say that Nu pays a kind of insurance against exchange defaults by not providing liquidity directly and paying people to provide liquidity instead.
Supporting non-NBT/USD needs to be phased out rather sooner than later in my opinion.
People who want to hedge BTC volatility with NBT need to make use of BTC/USD. That saves liquidity providers from the BTC volatility risk and is a little less convenient for traders.
But it can save Nu a lot of money and keep the liquidity on a more reliable level.
What would Nu do if TLLP liquidity providers decided to stop because of the risk?
How could the peg be kept?
Solely by NuLagoon (which is by design less responsive to people’s desire to stop liquidity providing)?
After the recent Bitcoin volatility events it might be the case that the pool compensation needs to be increased (or at least not be degraded) to keep the level of liquidity at the required level. We’ll see…
