Thanks. My buy order does not have any limit on it, so any number of shares which was below my buy price of $0.16 should be matched with mine. But, since 4k fill, I have got none.
I checked pps trend (I have not followed it for a while) now, it seems the pps was dropped recently to a new low. Someone is indeed interested in "controlling" it. Hope it has nothing to do with Guo or Guo's relation.
