BTL will not be delisted from Bittrex, we managed to have enough volume for the last 2-3 weeks... and it would be a shame if that happens. Allcoin has no volume at all, most of the trades are in bittrex and out of the 4 exchanges bittrex is the only one half decent. I strongly recommend to not lose it and to continue the dialog with the exchange owners. I will leave most of my BTL assets there and not move them.
Teodor, I have considered what you said and I will reply with a longer answer later this week.
