There are ways to mine however you need to invest some money. First issue is your electrical bill, if its like $0.10 kwh then its not worth mining anything. If its half that then you have some options.

You can get an ASIC however the latest ones are very expensive. At the current rates you will only make a profit if the underlying coin goes up in the near future. Hence you might as well just buy BTC and hold it.

You can get a desktop computer and buy a GPU like an RX 470 8GB and make like $0.25 per day per card before electrical costs. Same with getting a high end CPU like Ryzen and mining XMR. However the profits are small. There really is no point at the moment.
