While you're at it set tBTC price oracle to 70,000.00 ;-)

This proposal, if approved, will:

- switch DOT from the current `2-9-100` Supply & Borrow strategy, to a new `1-4.5-50` strategy - effectively reducing the borrow APY by 50% at every part of the utilisation curve
- change the PRIME price oracle to `1.024`

For background context on the DOT rate strategy, on the `14th` March Polkadot will reduce the rate of DOT issuance by `55%` - at this block specifically: https://polkadot.subscan.io/block/30354008
This rate change in Supply & Borrow will ensure that GDOT + vDOT looping remain viable strategies after the change.

- **DOT Strategy Change:** Switching from `2-9-100` to `1-4.5-50` reduces borrowing costs by half.
- **PRIME Oracle Update:** Adjusting the price oracle to `1.024`.
- **Reason for Change:** Polkadot is cutting its DOT issuance rate by 55% on March 14th.
- **Goal:** Keep GDOT and vDOT looping strategies working well after the change.
