what we expecting this to drop to?

$Meta Materials Inc. Class A Preferred Stock(MMTLP.US)$ anyone regret to sell earlier?

$Ocugen(OCGN.US)$ this hasnt blown up from government funding like NVAX, and they could also upgrade their contracts anytime soon, including more amendments to supply other countries, Mexico, Canada etc…. but keep thinking this is worth $12 and let the paperhands shake off and shorts try to take us down.

$Ocugen(OCGN.US)$ damn paper hands, hope you all regret it when you see this at $30 with everything good they have coming.
