I Built 30 rigs, each with 3 x 5830's which all and up cost me 15k which I purchased on credit cards at close to 20%. I am not making much money or bitcoins since the difficulty has gone up, I would have been quite well in the clear if I sold my bitcoins at $30 but I still have them, I don't want to sell them under $15.

Is the price of bitcoins going to go up, if so I will be alright but I am uncertain if I can continue to generate bitcoins in a profitable way. I still have to pay off the credit card. What do you guys think?
