Not entirely Bittrex's fault, but they DO bear some responsibility for ICOs they host.
The need to step up to the plate and put an end to this crap.
I haven't followed the coin very closely and didn't invest in it, but did they actually host it? I thought the ico ran outside of bittrex?
But I do think if they agreed to destroy the coins, they shouldn't have listed it on the exchange until the coins were actually destroyed. Not a biggie to wait a day or two before listing a new coin.
There is no guarantee that it would have mattered, as a dump could have occurred on baby-sized exchanges like c-cex and such... but it would have been less painful.
