I'm wondering, how are you people financing these mining rigs? If you have 30 cpus on QubitCoin which can't be traded yet (or at least not much), do you have another cpus on some other coin that covers that? If that's not the case, you must be thinking about it as a long term investment, but I still find it little hard to dump hundreds of dollars to rent servers and then hope that it'll pay back in a few months.
I read about a guy in the Memorycoin thread who rented servers for 200$ a month. It did pay of as he was mining.
