BTS is actually a coin I never expected would be delisted from bittrex anyway but they sure have their own reasons for it. BTG on the other hand still remains the fork of bitcoin which was not really necessary anyway, so delisting it may actually be something worth it.

However, so many decisions that bittrex has made in the past with respect to delisting of coins sometimes can actually be worth questioning as I still would not have seen the need for delisting it when considering there are so many shit coins listed on the exchange.
