Trading competition is good for the overall entities of that project, that is, the members, the exchange and the project in question. In the case of members, it gives them the opportunity to earn more tokens but however, they need to be trading experts. In the case of exchange, it helps to increase the volume of that exchanges as well as increasing its activities too. Finally, in the case of the project, it helps to increase the price while making the project to have more volume. So in all ramifications, I think trading competition is good, but make sure you are an expert before getting involved.
