So far enjoying the CEX.IO platform a lot. Nice use of some of my btc holdings and the buy sell platform is working very well. Completely painless and a way to make some extra BTC off part of my BTC holdings.
Yeah - I haven't looked back. Gets a bit addictive as well

It automates much of the messing about with mining, and yet still allows you to join in.
Gives me my forex type itch some relief haha.
