Looks as though Cryptocoin mining is becoming complicated and seems to need a nimble user to constantly monitor what to mine. Sounds like more and more work everyday. Dunno how you guys do it. LOL.
You either pay someone to do it (via a profit switching pool like clevermining or middlecoin), or you let others pay you and take the risk (via a mining rig leasing service such as leaserig.net).
I've done both. The switching pool is super lazy, just set and forget. You can get a fair bit more by leasing the rig to people who think they have found the mother lode, but it's higher maintenance, they tend to want support or refunds if your rig dies. In 1 month, I've only had to give out one refund (my ISP pushed out a router firmware update in the middle of the night, and the router didn't reboot cleanly afterwards, and I didn't realise until I woke up next morning when the house was like a walk-in freezer because all the mining rigs had shut off).
The other advantage is that you can see what other people are mining. My best customer normally mines on their private profit switching pool, but you get people paying a premium price to mine the latest new altcoin. That's how I found out about TOPcoin. I noticed someone had paid a massive premium to lease a rig for that, so I decided it was a good thing and pointed the rest of my rigs at TOPcoin. I made out like a bandit on that - got about 0.8 BTC for 12 hours.
The thing I'm really kicking myself over, is that people have been lease my rigs to mine aurora on and off for the last 3 weeks. I remember thinking, hmm I might try mining that, but the difficulty is over 30, it probably won't be worth mining at that high a diff. LOL
