Trading cryptocurrency is partly like trading stocks. Since there are assets that you can invest in purely out of the asset's fundamentals. Meaning that because the crypto is useful or has a real future because people will use it not just buy it out of speculation then you are sure that it will grow in price in the future. The problem is that there are coins that are just plainly pumped by people and some others are dumped. Those are hard to predict. It will happen that you can probably lose or gain big amounts of money because of those pumps and dumps. The best way to learn is always to jump into it, of course.
