there is not a specific date for list envion on HITBtc but soon HITBtc will list envion
and envion wil trade-able there
all we need is to wait. but my point of view holding envion for next 6 months will be much more profitable
after envion mining platform ready price of per envion will be high then current price
and i think current price is 1 $ but after list on HITBtc price could be more then 1.50$ in a very short time
