exchanges and marketplaces are a great place to start. However people need to actually spend the tokens on things.
Take for example spending tokens to buy Steemmonster (splinterlands) packs.

I feel spending on in game items will be a great 1st step. Gaming has always driven the computing industry.

What about holding conventions and merchants accepting the tokens as currecny to buy IRL items. I manufacuture good and would do this.

This also goes to the concept of burning tokens, as a merchant or game could take the tokens and be required to hold for a set time. This would remove from the active pool.

Just some thoughts.

Exchanges are great but the end gain i get for 'spending" the token is the most important step. Right now everyone seems to be trading token for token.

i don't have the answer but love having the conversation as together we can come up with a use case.
