Profit isn't much of a concern to me If I've learned one thing from breaking down several games, it's that if the product is successful, there will always be a way to monetize it. At least that is how I see it. That being said, I don't like advertisements very much so I'll try to keep those away although I might resort to them if I feel that they won't be too disturbing. I will also hold a share of vits myself so the success of the game and the currency will determine whether I make a profit or not! But the thrill of having people play the game should be enough to keep me satisfied.

Edit: forgot to mention that there might be premium options for things to buy in the shop like skins, that is also one possible way that I might look to make money if I need it.
