I'd like to be able to keep my MV games free and still make money out of them. A miner solution such as coinhive is the only way to do this without annoying the player with ads popping up every 5 steps. In previous makers it wasn't really possible (I don't know of any ruby-based miners), but with MV and its move to JS, it is. Before you balk, the miner would be set to 10% CPU and two threads only as to not be a strain on the CPU and (obviously) would only work if the game is running. It'd be probably pennies (unless I'd make something that becomes REALLY popular, but would be motivating enough to make games that players engage with and wants to play (again, the miner works only when game is running so if no one plays it, I don't get a penny) constantly. I need someone to make a plugin that can interface with CoinHive.
