The last few months I've put more time and effort into curating and engaging on other posts, rather than just posting.
An interesting thought based on your post. Would you consider buying into, and supporting, games on Hive as bringing value to the chain? There are people in Splinterlands bringing in a lot of money to the ecosystem, but not necessarily buying hive or spending time posting and engaging here. I'm not sure if that would be considered adding value.
If yes to the above, that's probably the main thing I've done...buying SPL assets and buying a decent amount of hive tokens. Sadly, I can't say that I've done much else to bring value to the chain.
I think engaging matters.
Sure, that's one way to bring value to the chain as well, especially if the games care about being on hive and know what makes it special and give back to it by marketing to their players why they should also use the social layer of hive.
That seems to be a missing component of the games on Hive. I've seen players marketing hive within the communities (Azircon, for example), but not necessarily the games themselves.
