I am currently in contact with a few exchanges to try and get GPUC back up to the trading volume we were at. It's certainly not good that our best exchange is now having difficulties staying afloat.
We need to promote the coin more if it's ever to succeed. As for the exchanges part, i agree with jimlite that we have to focus our efforts towards getting listed on mintpal. Some of us keep voting as much as we can but we need more people helping.
