Bittrex doesn't randomly delist coins for no reason. Their pages warn you of a delisting and tell you to remove all coins. This isn't a scam, they aren't going to spend money on a coin that is not making them money. That's how business works. I'm also pretty sure you can contact support and request your coins back after they delist the coin (not 100% certain).

It's not like your coin is worth anything if Bittrex is removing it. Quit complaining about pennies on the dollar and make sure YOU watch for delisting warnings.
