Poloniex or Bittrex are the bigger two that trade SBD. Both are having problems with their ID verification however, so getting into them seems to be a challenge right now.
I believe Bittrex stopped accepting new traders. I have been waiting going on 4 weeks to get verified there.
Poloniex is running behind on their verification process as well.
The only one I've been able to get into the last month has been www.binance.com/?ref=12587112 but they do not trade SBD
I have tried Poloniex, but I got problem on my verification., and I received a notification that I exceeded the number of tries in account verification... :(
Sad to know, because poloniex has higher rate in exchanging sbd to btc..
I have been waiting bittrex to accept new members registration...
Thank you for your timely response with my concern.
