for me bittrex was a good exchange..
because many exchange doesn't allow you sell coins after the points, like you have trx "4500.987" they allow you to sell only "4500"... ".987 " trx was lost.. bittrex allow you trade in points also...
one more thingh..
new exchange coming secure with zero trade fee, thread link- "https://bitcointalk.org/index.php?topic=3342829"
check his thread and join their airdrop if you want..
