I see you have loads of options already. Blocktrades was the easiest, even grandma could use that.. but..

I use Bittrex, pair BTC/STEEM - Sell order.
Pair BTC/WhateverCoinYouWant - Buy order - or just hoard BTC.
Hive pairs with BTC on Bittrex.

It takes a little getting used to but soon it will be like taking your jumper off while driving down the M1 at 90mph... you know... easy!
