Currently, staking offers a 15% annual return with hourly payouts. This rate will increase to 30% next week. After that, the rate will gradually decrease over time—first to 29%, then 27%, 26%, and so on, depending on factors such as network volume, the number of addresses, and infrastructure growth.
As an early buyer during ICO I really like this boosted APY and the way you decreased it to control saturation of the circulating supply from the rewards. I suggest that you will do the old style of DeFi which the APY is in proportion to the number of stake Jack tokens.
For example if the amount of stake Jack tokens increases then the APY decreases so that long term stakers will be rewarded more whenever someone unstake their tokens to sell.
