That one is clearly rotating. Magnetic levitation with a rotating field is not too difficult (you can get levitating flower pots as cheap novelty toys) but the sample in the new video appears fully static.

Edit: relevant Wikipedia: https://en.wikipedia.org/wiki/Spin-stabilized_magnetic_levit...

The video in the reply (https://twitter.com/xmal/status/1300794329347260417) seems to show levitation even when the magnet isn't rotating?

They're stacked to increase the field density.

The object that is rotating is a magnet. It's not what we're seeing with the flake which appears to be flux pinned.

If this is fake, it's a very well-done fake. I'm feeling 60% sure that LK-99 is RT superconductor at this point. It has theoretical support now since last weekend.

Most flux pinning examples on youtube allow rotation (With round superconductors and magnets, though.)
