One of my issues with all of these game developers opting to create a coin for every new game that are developed, comes with the limitation of the utility for these tokens. You can basically only use those tokens in that game and there are no real demand for that token for anything else.
you can trade these tokens on an exchange. the tokens nature is on video games so it's normal that the tokens will only be used this way. We can't say that these tokens will also be used on the mainstream market but there are tokens that are also built for that.
I think that the STONE platform will allow you to use the same tokens in games that are traded on well-known exchanges, as well as exchange them with each other. It is very convenient and will be useful for the entire cryptocurrency industry and for the gaming industry.
Of course, this is the main idea of the project so that you can use tokens already existing on the market and not create new ones.
