I'm gonna be honest. I don't have the time to be trading all the different alt coins, let alone set up miners for them and associated wallets. I have my 5770's mining over at Middlecoin, and it's doing exactly what it needs to do. It helps keep stress down, and it keeps providing. It has not failed me yet, but I've only been mining for 3 days. Let's see what happens, eh?
Also, I have 0.5 BTC with Cryptsy, only to log in one day and find that they have been auto traded for Cryptsy points. Yeah, never touching their services again.
