Some investment in the other companies listed on GLBSE perhaps ...

IBB looks like a good investment in terms of both benefits to the Bitcoin community and potential for profit.

The company has already made investments in two other companies, which have listed on GLBSE (BO and BST).
Both of these seem to have aims of earning wealth from effort, stimulating trade in Bitcoins.

Mining had its place, in stimulating interest in Bitcoin in the earlier stages, but I think it is done now, time to build demand for Bitcoin rather than build the supply any further.

Disclaimer - I am long IBB through GLBSE.
