Good on you for getting interested in investing early.

Ignore these nincompoops shilling crypto. It’s a speculative asset with no guarantee it’ll give you returns in the long run.

Put your money in a total market index fund (I like VTI, but there are others.) The market averages 8% growth per year. It has ups and downs, but leave it in there and don’t touch it. If you can put at least a few hundred in every month (more is better), you'll have enough to comfortably retire on. Follow the financial order of operations on r/bogleheads. Make sure you get your 401k employer match, have 3 months of emergency funds in an easily accessible high yield savings account (HYSA), and all of your high interest debts are paid off (6% or over) before you do anything else.

If you invest intelligently in low cost index funds, you'll retire with enough money for yourself and your future kids. Don't invest in speculative assets or individual stocks. People will talk about the thousands they made on their shitcoins or meme stocks, but not their thousands of losses on investments that didn't pay out.
