Fastest way to transfer funds from Ethereum address to Bitcoin address I have an Ethereum address with some Ether in it, and I would like to transfer some of those funds to a Bitcoin address. 

I am wondering what's the quickest and most painless way to perform the token exchange and the transaction - possibly without having to install a wallet client.
Use an exchange that trades both BTC &amp; ETH.
Bittrex, ShapeShift, Coinbase, Poloniex, etc.
