ICO with mineable tokens?

[dcn.cristi]

Hi guys,

I was looking for this everywhere, but can't seem to find the appropriate answer, so I will try to be as clear as possible.

Let's say that a great project needs to get funded, so they initially would use an ERC20 token for the ICO. After that, they need to swap those tokens for tokens on their own blockchain. Now, the project involves mining of those tokens. How would that be done without decreasing the value of the coin? Is something like this even possible? What other options would be, that would result in funding a project with tokens that require mining? How would the token distribution work?

Any helpful inputs are highly appreciated.
