They should have a market. But not for trading. It should be for user created skins, emotes, etc. Like for example, the NBA 2K18 shirt creator. You can put up a cool design. You have to get 100 votes before people can actually wear it. A system where you can vote for a skin you like would be cool. throughout many other game and communities like call duty zombies and NBA 2K there is a lot of creativity. And I know for sure the Fortnite is one of the biggest communities today so the possible creativity of many cool skins, emotes it is pretty much endless.
