I'm a college student (19) and I want to figure out where I should be putting my money into. I know that generally it's good to invest into Roth and Traditional IRAs, but since I earned my money through cash, I don't think I can. Should I just be investing into stocks / ETFs or is there something else I should be putting my money into? Or should I try to declare some of the money on my tax report and put it into IRAs. I worked as a coach and a stringer + a job in my senior year of high school for a good chunk of the money. I have around 7k saved up through a couple years of work / monetary gifts from relatives. I would appreciate any and all advice. Thanks
