It is possible to build a dApp that holds ether in the contract address and the underlying tokens are valued based on the ETH balance.

With this in mind, I want to build projects that earn USD converted to ETH and dumped into the contract wallet as a truly decentralized profit share.

So far, here are a list of projects I have done in the past that could be rebuilt and fit the profit share model:

-Advertising network (sell banners, interstitials, and visitors)
-Social media & Twitch.tv follower sales (via custom app for Twitch and SociPanel for the rest)
-A blog that earns Adsense earnings and from paid post sales
-PTC/GPT sites

Ideas on a larger scale:
-Solar farm powered Mining operation
-Solar farms that sell energy to the State
-Establish a "tithe coin"
-Implement Crypto as a national currency for a new Palestinian Nation in Israel or Jordan

I will be starting the project in 2019 and would like to know other ideas and also what would it take to get you to invest in an ICO for this? The purpose of the ICO would be small, an allowance for me to live off of so i can quit my job and work on it ($12000/yr for 5 years) and $12000/year for bringing 36,000,000 visitors per year to the site(s).  An additional $30000 for reserve to cover the costs associated with development (ie contractors if needed). All surplus fund would be returned to the dApp profit share.  A total of $150,000 for the ICO and 15,000,000 tokens created.

10,000,000 tokens would be held by investors, 1,000,000 by me and 4,000,000 as blog post writing incentives (get paid tokens to write blog posts)

If the personal support is not a good idea, I can do Lyft or Amazon Flex driving to supplement my needs instead.

Thanks for your input
