I read. But the main question which worries me is Vinex exchange and volume. I dont see progress in this. WHy dont you hire a professional PR manager who will be able help attract real traders to your exchange? You can fire at least temporary CMO from other similar succesfull projects (Bitmax exchange, Monaco etc.)
And you can make your exchange at least #1 national Vietnamese exchange at first. Vietnam is a huge market with 95 mln people.
