What are those hive-engine shitcoins for?

In the past week I have been receiving, frequently, some shitcoins that have no price/value, I have no idea what they are, what are their purpose, nor how to use them, but I have been staking them, so if someone can explain to me I would be grateful.

Do they have any usage? And if so, HOW am I supposed to use them and use them? I know that STEM one is from a community, but do not know at all how useful or what for it is. The other ones even less.


Does anyone know anything about them and can, please, clarify what are they for and how am I supposed to use?

There is a screenshot of my shit-hive-engine coins.
