There is no way that livecoin overtook bittrex. They know how to fake volume thats for sure..
If you notice that most of volume on Bittrex is Steem and it seems to be losing steem...
The most volume on bittrex is on whatever manipulators want it to be. They move from one pump and dump to the next. But overall i just cant believe people would trust livecoin with large amounts of bitcoin yet. they need to prove themselves first
