You can also try mining primecoin (XPM) with CPUs. dedicate 20-50 cores to it and sit on the coins as they should be worth something when bitcoin and the 50-60 other alt-coins loose some of the wind in their sails. XMP is the only coin that is still easier to mine with CPUs.

Amazon ec2 cloud may also be a good place to start some XPM mining.

Search this forum for XPM mining and learn more.. good luck..
