COVAL will never be delist from Bittrex. These are unfounded rumors.
Bittrex recently delete 80+ coins but COVAL stil there.
They never deleter active project, with strong devellopment and active communauty.
And I think I remember reading in the matrix chan than devs told to bittrex board than it will have release soon (but maybe confuse)
Totally wrong. Not too long ago Bittrex delisted BitShares, which has a vibrant community, good tech, a working product, very active development and currently listed at #32 on CMC.
