Are any Waves Platform tokens valuable?

I followed along with a @scatmandingo post (https://steemit.com/cryptocurrency/@scatmandingo/how-to-become-an-accredited-investor-if-you-have-no-money) and issued my first Waves Platform token:

Now what? How are such tokens used today? I see the 2018 roadmap (https://www.reddit.com/r/Wavesplatform/comments/7jlnu2/the_waves_2018_roadmap_from_todays_presentation/) lists "Touring complete smart contracts" in Q4. Are we all just waiting until then?
