Agreed. I had to try real hard to appease the Ponzi scheme crowd with this one. I just get this question a lot when promoting the site. “Isn’t that a Ponzi scheme?” Now I can say yes it is, just like the USD!! It’s based on the full faith of the community backing it up. If the community is growing and has ability to scale and offers a unique value mechanism, then you might want to look a bit closer! That’s why I love steem!!
