Hello there...Go ahead and start Mining!! Cpu mining is the easiest entry into mining coins. I got my start Cpu mining and I had so much fun that i created Uranium-X to be Cpu mine-able for as long as it can be. I would suggest mining at night while you are asleep. You can mine with a laptop...but the more powerful the computer the better the chances of solving blocks...Don't let this discourage you...We have older laptops in the field mining urx and they do solve blocks. i would not suggest mining with a 32 bit computer...The 32 bit wallets are for people with older hardware that want to have a Uranium-X wallet for sending and receiving coins.
