StackofStake announcing they will list SmartCash right after already listing BitcoinConfidential. They will be giving a passive income through SmartNodes and SmartRewards.
SOS is claiming to balance $SMART in the pool between SmartRewards and SmartNodes to find the best equilibrium for the best return of your investments.
They're offering an exclusive 0% fee for $SMART staking within the next two weeks. Then the rewards fee will be changed to the default 8%. Sounds like a good time to get in stake some coins.
SmartCash never get traction. I remember to see a lot of people promoting this one 2 or 3 years ago.
