How would you invest 1000€ at 19yo?

So as the title states, I’m 19 years old. I have a 1000€ I can afford to loose right now and I want to invest it as smart as possible. After that I can invest 100-200€ per month.

I have other savings and can live on those for quite some time, I have a car, I have an apartment. Do you guys have any recommendations? I’m from the EU.
