The yield from the BNB/SPS pool has dropped significantly. This pool was consistently generating around 40% APR, for an extended period of time. It appears that in the last week or so, a significant amount of new liquidity has been added - around half a million dollars worth it appears.
This may have to do with the proposal that passed which makes SPS DAO's LPs for BNB/SPS and ETH/SPS earn rewards alongside regular investors.
That would explain it - thanks for sharing this as I had not followed these developments closely. The yield is still decent, but it depends what SPS DAO is going to do with the rewards.
