It just mean that Pancakeswap liquidity is already depleting most probably due to competition of other AMM exchange. This is the right thing to do if you don’t have funds anymore to continuously pay stakers with there passive. This will not gonna kill PCS because they are already established and the number one AMM exchange in BSC. Maybe you are just frustrated in the decreased of the reward. Moving in Biswap is a smart move if you are chasing high APR.
I don't think it's matter of liquidity. I think what they are trying to prevent is overinflation. Their liquidity isn't really changing much in 3 months but their token supply keeps increasing without a sign of deflation anytime soon with the old design.
It's not that I'm frustrated, I'm just shocked. I woke up one day and the old design was gone, replaced with a new design that isn't really appealing to me anymore. The crypto world is changing so fast that locking your money with bad APY is just bad design, at least in my opinion. Their flexible is so bad that even staking in Binance yields more than the platform itself.
