What I've gathered from many of the discussions around this topic is that the levitation is a notable feature of superconductors due to th Meissner(?) Effect. So if it couldnt levitate, there would be no reason to suspect that it is a superconductor. Because it does levitate, superconductivity is one of a few possibilities.

There have been indicators it may be a semiconductor instead, but apparently the conditions to accurately produce the material are vague/not fully understood - so attempts at reproduction have failed to rule it in or out 100%

Which is also sadly a common component of hoaxes, include some vague component so you can just claim your detractors are doing it wrong.

Very interesting, had no idea of the meissner effect. Thanks!
