Compound interest is the 8th wonder of the world

There are "investment" avenues which could give you good ROI that I have read about where you could "loan out" to voting bots and earn more than you put into it - much more.
I have also read about the SP - Steem Power and how it could help you gain more power when used wisely or in collaboration with others who have similarly SP.
