GLBSE vs MPEX

[aura.flux]

I have a few bitcoins and I don't know what they are really good for besides making more bitcoins. So I am thinking of investing. Which one is better GLBSE or MPEX? Thanks!

GLBSE is user friendly and MPEX charges you 20btc to create an account. Bitcointorrentz and IBB are ok stocks and wont be affected by the block reward halving.
