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.
We did not host this ICO.
Although you did not host it, if you agreed to destroy coins, you shouldn't have listed it until the coins were actually destroyed. Common sense should have told you that there was a danger to having such a large premine sitting out there... and was there any real harm waiting 24-48 hours before listing the coin? Not like c-cex would eat up all of the trading profits going on. They aren't exactly an exchange juggernaut with tons of volume.
Except your time line is all wrong. We were asked to destroy the pre-mine AFTER the coin was already listed. No good deed goes unpunished. In the future we will likely not offer our services in destroying coins so as not to get dragged into these scandals.
Poor innocent little Bittrex. Collecting fees from scams.
Maybe if you weren't in such a rush to add every little coin without some proper investigation of what you were getting into people wouldn't "drag you into these scandals".
You involve yourself in them when you list the coins. No one forces you to add them.
