Thanks for the good tips. Many are very valid. Alot of people will tell me to look at whattomine.com and tell me how much they can earn in a rig. I told them this only happens if your machine can work 24/7 for you with no downtime and in reality, the payout is like 80% of what being shown in the website. And then with all the bios setting and hardward stuff, these are really long journey.
