I just turned 20. I live in germany, have a stable income and rent is cheap because i split it with my family. I could comfortably start investing 1000€ per month and was thinking of doing it through Trade Republic and invest into FTSE All-World USD (Acc). I plan on holding to that investment, i'm thinking about my future (30s,40s). I'm very new to this, i have 2 weeks until my salary to decide if i take this step or not and i would really appreciate some opinions on why i should or should not take this step.
