GLBSE mining bonds

These mining bonds on GLBSE sure do pay huge interest.

From what I can see, the technology that miners use is always changing. If you invest your money in a mining company making great returns today, you might not be guaranteed those same returns when their machines become obsolete. It might be worth investing your money in a larger mining fund that invest in many smaller mining companies. This well help protect your investment against severe losses.
