Wow, so I'm off by a month, why does it matter?
The 500,000 shares that Eno Richard acquired in April 2018 are currently worth the same as your shares, nothing.
--------------------
Fact check:
April 2018: Eno exercised his shares
May 2018: BIOA filed voluntary bankruptcy
August 2018: BOD & Management voluntarily resigned.
Math check:
April to May = 1 month, not 2 months
April to August = 4 months, not 6 months
