The sustainability of GameFi projects requires careful evaluation. It's important to distinguish between short - term hype and long - term value. Projects with a strong game concept, a large and active user base, and a viable economic model are more likely to have long - term potential. Additionally, factors such as the quality of the game development team, the ability to continuously update and improve the game, and the level of community support also play crucial roles in determining the sustainability of GameFi projects.
