I've used the ƀBTC (bitBTC) in my bitshares wallet to pay for a T-shirt, Rand Paul campaign contribution, and a https://cryptostorm.is token just this week, all via on the fly conversions from ƀBTC to BTC at BlockTrades (https://blocktrades.us). I've received about 0.0015 BTC as yield for holding my small stash of ƀBTC so far.
