What does it imply for a token to be helpful? The very best heuristic is whether or not folks wish to maintain it for some motive aside from as an funding. For instance, some tokens grant entry to blockchain-based services or products, much like how baseball tickets grant entry to a sport. Different tokens coordinate human decision-making, as with governance tokens, or incentivize human work, as with base layer infrastructure tokens. And even different tokens memorialize contributions to a system, whether or not it’s knowledge or one thing else precious (however that isn’t an funding).
