I think building on Contentos after the mainnet is launched would be very interesting. I think the team should also focus on marketing. People need to know what going on in the ecosystem (investors and COS token holders as well). I think thats going to increase COS utility and market value.
I would advise against that though. That move should only be made after they have gotten enough fans not tied to the binance ecosystem.
yup agree on you, it may cause a trouble because they only have few supporters , they need to make the project make on fame before listing on differnt exchanges.
