GPU mining is one of the types of mining. For such mining, discrete video cards are relevant, not integrated ones. In fact, any coin can be mined on a video card, but some of them are better suited and easier to mine. Because they have a suitable GPU algorithm. There are other mining methods such as CPU mining and ASIC mining. If you want to mine a coin like bitcoin, then choose the right bitcoin mining hosting service . You can earn on cryptocurrency by buying and selling it. I can note that independent mining is not the most profitable. It is better to choose hosting services.
