Why buy when you can mine, for free??
Mining isn't free....
?
I actually have one machine mining GPU coins. I dabbled in ASIC mining, but after doing the math, I sold my miners and put the money in coin.
My biggest problems with mining are: 1. ASIC miners depreciate in value too quickly when increasing difficulty is factored in. 2. GPU takes up too much space, use too much electricity, and create too much heat, and for the best GPU are overpriced. 3. CPU mining requires too many PCs.
So what is your simple, cost-effective mining strategy that beats just buying coins with your extra cash?
