Citron's report got it down, but I think such volatility is encoded in this stock it can easily go $60+ and then down and then back up again...
Getting in sub $20 would feel super safe to me.
Of course I wouldn't dare hold this long term unless something on the 'prove it works' side of things drastically changes. Right now it would be a search for greater fools... Leaves me to think whether there aren't enough safer stocks to make 100% with out there...
This is 2020. Rolling a carriage downhill and claiming you invented cars is totally fine.
Probably a 'fake it 'til you make it' kind of thing, this.
