@starkerz I have examples. For instance, if you go to smartsteem.com , there is an area to calculate your revenue (aprox), according to the amount you invest. If you think that would help, we can contact @therealwolf who is the creator of @smartsteem .
The thing here is this I realized that what @steem-ambassador is paying is curation rewards. What other huge projects are doing is converting or creating a VOTING BOT, and when people delegate into it, they receive a ROI according to the amount of SP delegated, according to the money received by the voting bot, and the current steem prices.
