I do technician work to make a little extra cash while I'm in school. Business is slow so I'm not really making any money, so I was wandering if there was a way to trade with my customers. Seeing a news article that claims hackers making money by mining off of unsuspecting computer users, made me think "could I do this legally". I would like to advertise my business as being *free *if they agree to the program being on their computer. That would hopefully boost the number of computer's I see and fix. I just wanted to know if there are any programs to where I can set the customer's computer up to do lite bit-mining (preferably a program that fluctuates with the users computer usage for windows or Linux). I hope to see this as a long term thing so I can stack up the number of computers mining for me.
