I think I mentioned them in another comment to one of your posts, but in case I didn’t...

SPInvest, BRO, Archon (?), EDS, SIM* are all saving &/or hold/drip tokens. If you delegate HP to brofi you get BRO, which drips a handful of other stuff.

SIM is the currency for dCity, but if you hold more than 8k you’re eligible for a hive bonus, paid weekly I think.

Some need to be staked while others only held.
