I see that you plan token syaking for 2019.There will be some minimum set in order to join that program?
It would be good to have some minimum set as that will make big demand for tokens,eberyone will want to join staking and get DEAl tokens for free.
I don't think there will be minimum, but there are 3 different level of membership and that will affect the staking returns and options.
You are right, that will also affect your cashback option, how fast you can get it and how much percent, plus your staking in best membership option will give best return plus it won't be locked.
