I trade at southXchange as well, unfortunately very small amounts. I buy below: BTC 0.000002, but would love to sell above BTC 0.0000025 BTC or USD 0.02.

Although I think that selling below BTC 0.000003 BTC or USD 0.03 does not reflect the value of the coin. This price still does not cover my electric bill, but will it ever?

Personally, I think we need that one of two things to happen, that the price of GRC goes up:

1. One of the projects or a new project puts up a commercial project: Something like gpugrid.net introduces a WU for a Pharmaceutical Company, and rains GRIDCOINs to user crunching these particular WUs.
   Or:
2. A Computer Hardware Company / Internet Shop sells its products for GRIDCOINs - not for profit, but as means of a philanthropic marketing effort. Something in line with IBM supporting worldcommunitygrid.org; just not one project, but the whole BOINC environment.
