The real problem is fixed mh/s mining bonds. They are the worst wealth destroyers Ive ever seen. Youd be better off investing your money in hookers and blow at least you would get something out of getting "screwed"

Fixed bonds are horrible, I commend EskimoBob on his thread going over that.
The valuations Diablo traded at did the most damage, but yes, fixed mhash bonds in themselves are so horrid.
Even with the upgrade that some lucked out into and are trying to resell, most will have lost money (how bad would that niche have been hit if BFL didnt do the tradeup thing?)
