Note that over three days, assuming the same level in market crash every day, this exposure would be 1-(1-47.5%)^3 = 85.53%. Starting from a safe collateralization ratio of 250%, the loss in this ratio would amount to 213%, which would leave us with a 37% collateralization ratio if it happened. This is below the 100% parity level. In this case, a cut of 63% of the 250% EOS collateral ratio must remain liquid and reserved for potential liquidation. Furthermore, at least 133% should be in reserves if we wish to satisfy the 170% critical level. We can then consider staking the remaining collateral for three days.
