You can trade BCI on stex.com (formerly stocks.exchange), but I've never had a positive experience with them and they have a bit of a shady reputation. I'd wait for hitbtc or bitfenix to open their wallets again personally.
stex.com (formerly stocks.exchange) is a good exchange. No problem for me for 10 months.
I made many trading on this exchange. Mostly: neoscrypt, cryptonight and x13 coins.
