Re: I'm new. What do you recommend as mine?

in Minergate I can't mine with GPU. My CPU is a Dualcore.

recommend another software to mine?

The time for mining Bitcoin with CPU/GPU's is long past. Mining programs don't even support them anymore. You need to get an ASIC device if you want to mine Bitcoin now.

ASIC device? What is that?

ASIC stands for "Application Specific Integrated Circuit". ASIC Bitcoin miners use chips manufactured specifically for Bitcoin Mining. They use much less electricity than CPU's or GPU's and are thousands times more powerful.
