Impressive gains. It's amazing how Splinterlands is an ecosystem with so many options to earn money. I'm buying DEC like crazy to earn more SPS. I've also been doing very well creating content on Youtube and 3speak. Which I use to buy cards. I still don't earn that much in battles but I hope to get to those levels.
The only thing I still can't figure out, is understanding monster-curator curation. I never get SPT. Maybe he doesn't like the Spanish content. XD

The curation is done manually I think and depends if they like and find your content.
Another way to get spt through monster-curator is by delegating (part of) your staked spt to monster-curator and you receive daily spt as a reward
