I stated facts about PTSC, you replied with suppositions about EDIG.
EDIG may well have sustainable product revenue in the future. They have a product which they are marketing, and are continuing to improve upon.
Everything else in your response is possible, as are many other possibilities.
I see no reason to suppose EDIG will follow the same course as PTSC.
They are different companies, run by different people.
One would have to disregard the current facts, to see them as the same.
My observations, and my opinion.
