Even im new on trading i would still prefer bittrex because its reputable and been operating for longer days already and i didnt even heard about livecoins it maybe famous for someone but not for me. I will just stick to old ways since there are lots of exchanges out there and we i should bother to put up money on an exchange that i didnt heard of.
and there's also good volume inside bittrex so we can make big deals as well and like what you have said bittrex already established their name as a good reputable trading exchange and there's many investors and traders out there.
Im really checking out first the volume of coins that are being trade on a particular exchanges before i do use it just like what you said bittrex had good volume which really indicated lots of people do make trade with them.Just like poloniex, bittrex is good too and also c-cex.
