Sounds like a HIVE curator saw your post, liked it, and decided to give it a boost. Nice! HIVE gives back what you put into it. There's an enormous userbase branched off into different communities. I've only scratched the surface myself.

We all have our own level of investment with what we stake. The more you put in to staking, the more it helps everyone on HIVE. And the community shows their appreciation when we build up that HIVE Power. 👍
