Ok, I will try which is the best and I will buy new cpu to mine too.😀

CPU mining went the way of the dinosaur going on six years ago. So I wouldn't bother buying a new CPU just for Bitcoin Mining.

cpu might mean "central prospecting unit"

I think those were obsoleted by the "General Prospecting Unit's"

Which were in turn made obsolete by the Automatic Shovelling Integrated Circuit

Which in turn requires a more efficient shovel every 3 to 6 months.

I miss the GPU days.
