Well done Hive account@knowtheblock! Changelly fee is just 0.5% of your transaction. There is another very good exchange known as shapeshift https://shapeshift.io/#/coins . To use shapeshift, you don't need to register. Summarily, both exchanges are good, but it's always good to have options. I see you are new. A very warm welcome to steemit. STEEM ON!
