Guys it is unfair to blame Bittrex or any other exchange that adds a coin. The answer is sometimes right in front of you by applying good common sense and looking at the risk indicators. By looking at a few things you can make a call on the residual risk of a coin based on risk factors and then see how that fits into your risk appetite. You can then either stay away or risk it all and the alt-coin exchanges currently just provide a vehicle to cater for the whole of the spectrum of risk appetite.
In the absence of regulation in alt coins (self or otherwise) you can do certain basic things to protect yourself: Elite was high risk based on such an assessment, refer here

I think the eco system will change to a reputation based new coin release, someone will have to come out and said I was this successful coin dev, and I am making a new one for people to mine.
But there are too much spare X11 hash power out there, look, someone still throwing 2G hash at LTCX, a coin long dead.
