I had this same question. The answer is really trust. We are trusting that developers will use the profit from Tin Elementals to prop the price of CAIx. It's just another way to pump the price of a coin, really. There is no direct relationship. This is my big problem with this project. At any moment the devs can decide to keep profits in any currency they want, including fiat.
My guess is they thought using a crypto would be the best way to create demand for their games. If they screw the holders of CAIx, then they lose trust and a community interested in their developments. This is the relationship that binds the unwritten contract between the devs and CAIx holders. How strong is it? It's anyone's guess.
In any event, I'm willing to support the project based on this thought process.
The only way to create REAL demand for this coin is to make a good product (game) and have CAIx as the only way of buying/paying for it, everything else will not work in the long term and is just mambo-jumbo.
I agree. Building a crypto community will give them demand for their developments. In the infancy stages, it would be wise for them to honor the deal. But, if their games take off, they can easily abandon the crypto community and continue with developing mobile games. It's just another way to price pump and in no way would I consider CAIx equity in anything.
A real link between the games and CAIx is needed to make this work.
