Usually, insiders do not sell their shares; since they control the company and can if it is a fraud already have the $$$$$$ from the stock offerrings previously. But I think ZSTN should come out of it in a year time!
Several Chinese company's insiders steal the secondary offering money, Personally, I hope company has conscious, do a 2-3 million dollar stock buy back, they will set the floor for the stock. Otherwise, if you look at other chinese pink, other then CMED, none of them can hold on the stock price after 3 months.
Yes they have to file:
1) Only registered Market Makers are allowed to
participate (there are presently 230 registered
Market Makers throughout the US).
2) This includes those with pink sheet listing.
3) Pink sheet listing takes a considerbal length of
time to happen-even those that are a suspect of
4) There are many Pink Sheet commpanys that were &
still are legitimate-they just could not meet
Postscript: If you are trying to immply that this
will happen very soon with ZSTN you are very much
