Friend says investing in stocks is better than crypto

I don't have enough information and the stuff i read are a bit too technical for me to understand and then explain to others. I love crypto because it's fast and it's the only international currency available in my country. But as an investment, i'm really not sure what's best in the long run. I'm a bit skeptical when it comes to crypto because it's so fragile. Any news can affect it and you are more likely to lose your money overnight than stocks. If you truly believe crypto is the best investment, can you in very simple terms tell me why?
