Yesterday I decided to give a try to bitcoin and see what happens, today, I have a couple of newbie questions. I think that mining is my best choice, I have a geforce 9500 video card so I downloaded DiabloMiner for Linux, registered an account at mining.bitcoin.cz and started working. My first question is: should I keep the mining software working without interruptions or can I stop it whenever I need the computing power? The second question, do I need bitcoind to be running while my miner works? Why?
