total stock index fund or the S&P500 at 17 pick one of those two funds, put 50% of what you're willing to invest in a Roth IRA 50% in a taxable brokerage account

personally until you have a lot more money, skip the individual stocks & crypto, down the line if you have a solid financial foundation and want to throw $50-100 out of every $1,000 into a long shot for fun... not a big deal but for now keep it simple and honestly boring
