100% BTC at 18 years old while being a student

Hi. I just turned 18 and I don't want my money sitting idle in a savings account. I'm studying medicine and, honestly, I'm lucky that my parents support me with all my expenses and are there for me in any situation, so I can put everything I earn/receive into investments.

My goal is to accumulate as much BTC as possible. I've already invested $600 USD and the plan is to invest $150 USD every two weeks until the next halving.

Since I'm just starting out, do you think it's a good idea to take advantage of not having any financial responsibilities to go "all-in" on crypto? Or should I look for something more stable like the S&P 500 even though I don't need the money soon?
