In my case, I have been providing liquidity for 1.5m overall for 5 different pools which are as follows.
I put 93NBT as seed money 1.5m ago and the value of my fund on 15JUN15 is estimated to be 90.5 USD at current CNY and BTC prices against USD.
I earned roughly 7NBT as rewards.
So in the end, I am in the black: +4.5 NBT.
This is 3.22% monthly return.
But I am not sure if I was lucky or not.
Also, from Nu’s perspective, what was the value produced by such a liquidity provision?
Financially speaking, it is obviously a pure loss since I do not think we issued new NBTs in the mean time.
One way to nullify that loss or to drastically reduce that loss is to make the traders that use NBTs pay for that liquidity provision service.
That is why I think we need urgently to impose a higher minimum spread as I started to talk about here and as it is mentioned here by @dysconnect and then the needed custodial grants for liquidity provision can be reduced.
