I don’t have pictures, but a 20% LTV (loan to value) just means that you can only take a maximum loan of 20% of the value of your collateral in USD in order to keep getting rewards. So, the proposal is to allow for a 35% LTV.
So, as of now if you have $1,000 USD of ICX the max loan you can take out is 200 bnUSD and still get rewards. This proposal would allow for up to 350 bnUSD loan with the same $1,000 USD of ICX collateralized: $1,000 * 0.35 = 350.
So, you can take a greater percentage loan and still receive rewards, and the point at which collateral is locked would also increase to that 35% LTV.
If your loan becomes greater than 35% LTV, then your collateral will be locked and you will be inelligible for rewards.
