I am 17 years old (almost 18) and this summer I worked hard to buy a gaming PC to be mined. Before I only had a 2nd generation Intel CPU, it did not gain much and the choice of crypto is very limited. With my gaming PC I have an Nvidia RTX 3060 unfortunately it is LHR. But miraculously most mining software has managed to work around the problem. Per month I earn about $ 40. I live in Canada and more specifically in Quebec. In Quebec it is the French-speaking province and the cheapest in electricity, the price is $ 0.07 per kWh. So I am almost all the time profitable. The graphics card cost me $ 600 so I should make a profit in 240 days.
