This is not a trivial problem. Basically, imagine the usd deposited on CCEDK to have a different name, like CUSD. Now imagine an exchange like bitfinex where the deposited USD is much more liquid, and pretend usd on bitfinex is representative of the real usd price. Now imagine BTC/USD != BTC/CUSD. If we are pegging NBT to USD on one market and NBT to CUSD on another market, there is an opportunity for arbitrage. That arbitrage is being paid out indirectly through the pool compensation.
Does Nu want to pay to force CUSD=USD? Is this part of our business model and advertisement, that we can help exchanges align their local usd with the global usd despite illiquid markets? I just want to be sure we know what we’re up to so we can advertise it effectively.
