A big Ponzi Scheme ?

I suspect no one of those companies are designed to be profitable ever.
They have big losses because they sell below cost to gain traction. 
All cloned companies seem like bubbles.  

They are full (in excess) of phantom companies, shell companies.
And not only they have lots of phantom companies, shell companies. There is a very complicated and intriguing interlace of them. (very suspicious situation)
