x11 seems to be best right now as x13 profit has dropped like 3x since few days back..
X11 and X13 are uber crap.
Not even profitable to mine with GPU's....
Yeah, right, so you suggest we'd all start mining scrypt again? Or why not SHA? Seriously, X11/X13/Jackpotcoin/Talkcoin/any other exotic algo, are the most profitable ones for GPU miners ATM.
Not only does it use less power and generate less heat, they also don't have the competition of überasics, maybe an FPGA here and there, but that's about it.
Actually, the newest trend is just to keep on inventing algo's. Let's see where that will bring us
Mining still has a bright future, even for you, if you know what you're doing.
