I'm not sure whose selling but it's possible to track it easily enough.
This whole thing really is a test for how interested the wider crypto community is in Leo.
It wouldn't surprise me if some prominent members of the LEO community are selling CUB hard, given that so many of them have dumped Hive and are proud of the fact, that's almost like a badge of honour in LEO.
It is a finance community after all.
