Testing: Changelly, Blocktrades, ShapeShift

So I wanted to exchange 10 Steem to Bitcoin as fast as possible.

#1

Winner is Changelly with a 10 Steem <> 0.01573716 BTC rate

#2

Second is ShapeShift with a 10 Steem <> 0.0156488 BTC rate

#3

Loser is BlockTrades with 9% less than the winner 10 Steem <> 0.01559856 BTC rate

Conclusion

It makes sense to quick check those three before you actually exchange, to get the best rate possible. It's still much faster than going the exchange route, but literally 9% cooler :)
