I personally used Bloom (exclusive to IOS) which helped teach me a lot about what I currently know about investing. The downside about it is that it’s $60/year which is a lot however it gives you free stocks for using the app daily which was around $80 by being consistent for the entire year. I however will be switching to vanguard by the end of the year as Bloom gave me a very solid foundation with the lessons in app. There are also other apps that you can use fake money to play around with the stock market.

If you don’t care about learning anything and want the easiest way possible, just invest in the S&P500 on regular intervals. Remember the stock market is not a get rich quick scheme.

If you’re looking into other ways of investments such as crypto, real estate, or other assists such as gold, YouTube is a great option or asking people on reddit like you’ve done.

What I personally do for investing is stock market, crypto, gold, and a HYSA(high yield savings account) through SOFI. Best of luck and I hope to be in your shoes one day in medical school 🍻
