Turn our PCV into fractional collateralization pool. Starting by fully back our FEI with USDC (or other stablecoins, or even RAI and FLOAT and peg FEI to $1)
Change all ETH to USDC, and use it to fully back FEI.
using FEI price, to adjust the collateral ratio to include TRIBE in future as collateral together with USDC.
Basically turn FEI/TRIBE into something very similar to FRAX/FXS, which is proven to be working very well.
