Staking rewards are usually only 3-14% per year, but AMEPAy applies 300% then 150% ^^ Too high APY is also a problem that I used to concern, because it can cause the price of AME to drop deeply. However, AMEPAY team believes that the demand for AME of the market will be very large and currently only 250M AME exists in market, remaining number of AMEs will be locked. I also think that VIP staking with high APY will only be maintained for a short time.
