i find blocktrades gives u in both direction often a bad exchange rate as it tries to conduct the exchange quickly, and not lets you do arbitrary orders... lots of markets such as coingecko have though already listed hive and i believe bittrex lets u trade hive already

but as you can tell the market has not reached stability yet, which is why this morning i saw hive to hbd exchange rate at 0.49, and then bounced down to 0.31, yesterday it was around 0,26 or so... and only yesterday the 24h market volume reached 1000 hbd, while before it was only a few hundred dollars... so any real price i tell you now would probably not be true when you check your hive :P its deffo many times higher than 0.09 usd
