Talking about coins/tokens with practical usecases without adding ETH and ATOM makes this thread incomplete. We have seen how many useful dApps on the ETH and ATOM blockchain, be reminded that they pay ETH and ATOM to create this DApps. So I think they have a practical use case. Also some real life entities and companies have started accepting Bitcoin and ETH as means of payments. With time, more tokens will have more practical usefulness.
