Did anyone notice that, one crook had sold and bought NNW at 0.165 for the same lot of 9091 shares?
I have watched NNW recently and realize that this stock had been manipulated.
For example, today, the stock was offered at $0.165 for the lot of 9091 shares and it was then executed at $0.160 for 9091 shares. Right after that, he was bidding at $0.165 for 9091 shares and it was again executed at $0.165 for 9091.

And the other days, same mode has been used to drive down the share price whenever the share price gained momentum
Any idea who should I contact to investigate? Any advice is highly appreciated.
