Make a stablecoin backed by CAKE, called PUSD (PancakeSwap USD).
PUSD's market cap will be controlled for CAKE and PancakeSwap's safety and future.
PUSD's marketcap will not be allowed to surpass 10% of CAKE's marketcap.
PUSD will only be sold on PancakeSwap.
To control PUSD's marketcap, once it's past the 10% limit, PUSD will be more expensive than a dollar. If PUSD gets bought for more than a dollar the added price will be used to buy CAKE then burned. One PUSD will keep getting more expensive relative to the dollar as the percent of PUSD's market cap goes up further to the 10% limit.
One PUSD is exchangeable for 1 dollar worth of cake and vice versa in normal circumstances, but if PUSD's market cap goes up the 10% limit, exchanging 1 CAKE (let's say 1 CAKE is 10$) for PUSD will not give 10 PUSD because it's up the limit. However 10 PUSD can be exchanged for more than one CAKE, if the price is above a dollar, this will still have the fee.
Selling PUSD for CAKE will have a 1% fee, but buying PUSD does not. Fee will be used to burn CAKE.
PUSD can be staked to earn cake. With low interest rates, lower than what you would get to stake CAKE to earn CAKE.
PUSD staking will also have lock times. similar to CAKE staking, this will have afterburner and multipliers effects.
PUSD is not the best stablecoin, but it's safe, 100% backed, sustainable, and will not cause a crisis like Terra has.
