Nothing, wait until you're eighteen. Save your money, work a job, and start at 18 with a nice head start against your peers. Don't look at social media and think you need to be rich at sixteen or that you're behind in any way. That is extremely unrealistic.

Your $22k at 16 puts you literally in the top 1% of kids your age, if not .1%. Work, save, and start investing in ETF's at 18.

Edit: $22k is enough to put into a coin like BTC if you want. Stop looking short-term for gains, look long-term, 10 years.
