Yes, you can earn SPT from blogging and being engaged on the splintertalk.io platform. Basically, you want to either join the weekly challenges from the @splinterlands account (those will mostly get upvotes on Hive), when you put some effort into your post (tip: making a custom thumbnail image already does a lot!) you are very likely to get picked up with an upvote from @monster-market which hold the majority of the SPT since passive investors who don't have time to do manual curation delegate their SPT allowing them to get passive returns as 50% of the upvote value goes back to the curators.
- Make some quality blog posts about the game or join the weekly challenges from @splinterlands account.
- Engage in the Community
- Earn Hive & SPT
- Stake SPT & Delegate it to @monster-curator (or do manual curation)
- Get Tripple daily passive returns as SPT earns you more SPT and increases your SPS airdrop points generating passive SPS which you can stake to get a yield on top.
- Compound everything and save the Hive you earn for when Chaos Legion is released.
This is right now probably the best way to organically grow in the game.
Good Luck!
