Sorry for the newbie question. I realize I'm pretty late in joining the cryptocurrency bandwagon. I do not have a GPU or an ASIC miner, hence I absolutely can not mine bitcoins. I have an i5-2500K. Which currency would be the best to mine on this CPU? I am currently mining primecoins, and I have joined a pool as well. Is dogecoin going to be better? How about Quark? Since I am pretty new to the mining scene, I prefer a GUI miner over a CLI one, similar to what ypool provides. I also prefer coins which can be mined on Linux over others. Having a wallet for iOS and Android is a big plus. Also, since I plan on moving from physical currency to cryptocurrencies as much as I can, I prefer a less volatile currency. Bitcoin looks extremely volatile. A while ago, it was $1000+, now its less than $500. Also, which bitcoin exchange is the best? btc-e? I'd rather not go with anything which had any ties with Mt. Gox.
