I often looked at mining software and for the most part if you have an older gaming computer you might want to micro earn with it. There is a lot of place to rent out your hashes or pool if you don't have a large mining rig. There a few place to buy ASIC Mining rigs and they might be able to make a bit of money but you will have to buy the machine first and pay for the power. The only problem is when you go to download even good mining software it may look to your anti virus like a virus because the software controls your pc..
