I dont know why bittrex waiting ! I tweet them a lot and the coin is on POS phase now with rather high volume

I dont know why either! Don't let up on the tweeting! I would say drop them a message on their IRC chat as well at #bittrex. They will have to succumb to community pressure eventually!

Whitepaper will be announced tomorrow 7/2/2014. This will give you more details on plans for future development.
