Well...i did a little more digging and i guess the reviews aren't that good...but they have the largest list of USD trading pairs i've seen and i've had no problems with them in the past...so take it with a grain of salt..im sure we will see more exchanges with these pairs..i hope bitshares lists more , because i'll just stick with them...I've noticed a substantial rise in volume on Bitshares these last 2 months...pretty impressive
