I have to spare €700 a month

Hello everyone, here's another real post. I am 19, still live with my parents and am a student. I currently have €700 per month that I would like to invest. I don't have an emergency fund, as is actually recommended, because, as I said, I still live with my parents and therefore have greater financial freedom. I'm a complete beginner with no ongoing investments. In the past I have experimented 2-3 times with small sums (€5-10) in certain companies
