I respect what you are trying to achieve and hope my comment does not come off as an attack - that is not the intention.
With that said, I oppose this proposal.
The recent sudden increase and subsequent decrease in price were caused by a few entities manipulating the price by injecting huge amounts of ETH into the mutual. There were multiple transations of 1000 ETH and subsequent selloffs.
This were done after the discussion and voting on the proposal to change the MCR% had begun. We discussed the risks and potential short term effects of the proposal quite in depth before it were made and voted on.
- It takes about 7-10 days for the MCR% to stabilize in my forecasts.
- The fastest we can vote on and implement a new proposal is 7 day.
This means that if we are going to see the NXM price decrease during the next couple of days, there are nothing we can do about it now.
The good news is that after the change we should see growth being driven by providing insurance. With a higher MCR (that is lower MCR%) we will see better returns from staking, since a larger percentage of the capital in the mutual are used for providing insurance.
