One thing to be aware of is due to the massive size of the Pcv right now, arbitrageur can buy massive sums of fei without raising the price and still make out with a profit at the time of redemption. If whales swoop into FEI right at this moment, it will cause a huge loss to collateralization ratios for everybody else.
even 0.9 redemption is highly dangerous right now, 1.0 will mean guaranteed profit for people sweeping in at this moment
I dont know if it is possible, but the redemption should exclude people buying after the announcement. An alternate solution will be only to offer buyback for genesis participants.
there is money sitting on the table right now to be robbed
