There are also a lot of coins that are 100% premine and are stakes in nature but the 5% interest is quite low don't you all think I have one coin here where the reward is 100% ,why did you not increase the staking rewards to benefit all the holders?
It could be modified in the next wallet, but 5% seems to me to be a reasonable number.
Too much 10 - 20% interest and it will end with inflation and a falling value for RBT.
Too low 1-2% and it isn't worthwhile to even have interest.
