I wouldn't panic too much, in October they announced that Bitshares BTS would be removed from Bittrex. Bitshares is now top 35 in market cap. They announced it on Oct 3rd, Bitshares proceeded to drop from 6 cents to 5 cents before exploding to 60 cents and then to 88 cents.

Won't derail its progress in the long run because some other exchange will recognize its potential. All it screams to me is buying opportunity.
There are other good exchanges that Myterium can be listed if Bittrex continues with the delisting. There is Binance, KuCoin and Cryptopia just to name a few.
