If you're looking for some boring concervative investment advice, just set aside $X/month(or year) and invest in Berkshire Hathaway. BRK.B specifically.

They're a conglomerated that owns everything from investment banks to real estate property to soft drinks to car companies. They're well-managed and tend to perform in between the DOW and S&P year over year. Getting in the neighborhood of 7-10% annual returns is standard. But barring some kind of crazy growth year like 2020, you're not going to get Bitcoin scale returns.

If you're looking for something more exciting, just know you're taking on more risk. ARK Innovations ETF (I've sometimes heard referred to as The Ultimate YOLO by investor buddies) has a ton of leveraged stakes in tech companies like Tesla, Zoom, and Coinbase. Incidentally, the NASDAQ slump has it down nearly 50% from its peak. So if you're looking to gamble, that's not a bad place to start. But there's also a change the Fed interest hike fucks the entire FinTech sector and sends that ETF into the toilet.
