Given that now we are looking at possibility of raising MCR to 120%
Considering the other proposal of 250% might be making iAsset not as efficient.
We can look at a lowered initial margin ratio of 150%
CR<120% - liquidated
120<CR<150% - Unable to withdraw ADA or mint iAsset (deposit/burn mode only)
CR>150% Able to withdraw anything above 150% and mint iAsset and all normal actions.
