Why does Binance keep reducing staking APY rates?

I've observed many occasions now that the staking APY charges usually hold reducing, even throughout e.g. a locked staking interval. I feel that's not truthful because I end up shifting around my investments to re-optimize the staking APYs commonly because of it. In case you determine a sure fee is sweet you will start staking simply in order that they randomly lower it and perhaps make it not value it subjectively speaking. Perhaps some individuals choose to take a position in a different way then however locked staking makes it exhausting to redeem your coins through the staking interval with a delay and you lose your accrued interest. I saw steep drops on BNB locked staking APY charges and in addition lately on secure coin flexible staking. What's the cope with those? Can Binance agree on certain charges and announce modifications early enough to allow customers to organize for it more simply? Thanks for any opinions on this.
