The ones with points are guaranteed to airdrop, so you might aswell...
At least Grass, which doesn't require any liquidity at all to join. You just leave it running in the background...

Eigen, ZeroLend, Swell, KelpDao, all have point systems, but those require liquidity.
And if you up for it, you can also do $BLOCK, $PARAM, $LOL and onunblocked.
They all have points and don't require any liquidity, just requires you o register and tweet about them.
I'm not going to get rich because of this, but at every few extra sats helps long-term.
