I haven't gotten into DACH Token. There are just too many investments around. So far I'm just focusing on finding as many planets as possible and maxing out my Meta Skill level. 1K DAU isn't a large number at all. The plan is to be an Orca when the game does take off.
Active exploration brings few Stardust and Blueprints. If you have some rare Blueprints and build ships to sell, that could become the best money maker and I do see a real potential in this. But as you said, there really isn't an easy way to get exposure. At least with @steemmonsters you can rent cards or rent accounts to players and split rewards.
