There have been huge chunks of MYDX shares being sold at a time. That is an indicator of dilutive shares being cashed in. Could it be everyday investors doing that? Sure, but I highly doubt it.
The reverse split, in my opinion, is more likely to happen. The BS accounting math in cherry-picking specific numbers in the financials is worrisome too.
In order to finance these lofty ambitions the company has made, it requires money, issuing more dilutive shares and/or toxic financing.
