I am happy with @blocktrades so I don't think I'd buy/sell Steem/SBD from other platforms even if it becomes available there. We could buy/sell 1 STEEM/SBD with DOGE from BlockTrades which cannot be done from Binance. I could'nt find Dogecoin listed at Binance. Maybe I need eyeglasses. LOL
I like Dogecoin for buying/selling Steem/SBD because of LOW transaction FEE. Binance minimum buy/sell and transaction fees are quite HIGH for me. I will only use Binance to buy/sell coins that are only available at Binance. ;)
