The airdrop for the smart ring CUDIS @CudisWellness is available for claiming, check yourself.
Previously, Mr. Jeni made a ring and activated it, but I didn't intentionally wear it to accumulate points, so I just got a low guarantee of 3000 $CUDIS, which is about 300U.
Looking at the claiming instructions, even without a ring, you can still accumulate points to claim the airdrop.
