How much should this AppCoin/DApp be valued at?

[Joint Force]

I'm releasing an AppCoin/DApp with a new blockchain and reputation system to create a "living economy". It's formally a fairly popular App without a blockchain. What valuation would you give this? I'll be having an ICO with a set price. No over selling. Once the available coins are sold the ICO will be over.

It's currently an App. I'll be adding in a blockchain with digital assets. Then it'll move to being a DCO, Decentralized Co-Op, or a DAO.

I'll get in on this idea if it's around 2 to 6 millions USD. I wouldn't want to pay more than 6 million USD valuation. That would give me lots of potential profit if this goes to 120 million USD like steemit did.
