Yeah man I've been into the HE tokens as well! I think I started 2 years ago with them and bought a whole bunch. Some of them I'm sad to see fall off and disappear in value like SPACO (it was a Spanish dedicated token for the growing Spanish speaking community on here.) I was a whale in that one! I have 25k of the token which is one of their larger stakes and loved getting curation. Sadly the account behind it stopped funding it's account with RC so it stopped issuing tokens because it never had enough credits and I think they shut it down.
Neoxian is another good general use token and I've been enjoying stacking a bunch of those. I thought it was originally for Splinterlands focused content but it looks like it's not, so I've been using it and have over 40k now I think, and constantly growing!
I've got a decent amount of POB but now that I know a bit more of the background, I plan on snapping up some more of that so I can get in while the getting is good!
