What happen to MNS around June 2016 ?

Hey guys,

I'm still doing my research on MNS before deploying any capital but struggling to find information and putting the pieces together right now. During June 2016 MNS was around $1+ then a massive downtrend to March 2021.

Can any one please explain the situation and development of the company through out the 5 years ?

What has fundamentally changed within the business ?
Contracts ?
Lack of funds due to C.R ?
Not fulfilling investors expectations ?
Issues with their supply chain ?
Speculations ?

I see a lot of posts but at the same time not enough to justify ones purchase with the exception of a few posters here. At this stage I am interested to hear why "I should not invest" in MNS" with proper reasonings.

It just seems like when Rinehart throws a few darts every one seems to be on board now...

Please feel free to share your thoughts.
