I responded to an ad where a guy has a mining service. He said 5GHS for $100 for one month. Im a complete noob, I would be doing it more for fun than to make money. Do I just need to give him my wallet address, and how would I make sure hes actually mining on it?
thanks
No, do not trust random stranger on internet. And you wont mine 0.125 BTC in one month with 5GHS because difficulty is increasing
