The other use was the token creation service, but that doesn't seem very popular. If the app is developed fully, I expect it to blow up like Pokémon, but like you said, without a tertiary reason, I don't expect the bubble to last very long.
Who knows, though, maybe it'll get accepted by some websites for online payment or something useful.
The token creation service is pretty popular. They've already had over 800 contracts deployed using it.
Are they going to scrap the token creation service because that is the only reason I even use it.
