Greetings, chbartist
I think the steemit can work using the compound interest system. I see that the more sp the person has, the more sp and sbd he gains here in one way or another. Besides the person being able to earn more sps with postings, if she has a good amount of sp, she can rent it for some curatorial project and earn something around 2.5% per month. In this system of compound interest, the more the person has, the more he earns. If she does not withdraw the money and let you invested here, your return in the medium and long term will be infinitely greater.
Thanks for posting and good night !!!!
very good concepts and theories @julisavio
