That's how being a beginner is the best way to start investing? Where should I do it in general? There are a lot of options, but I am looking for proven ones.

Yes, I agree with you, there are too many options for investing in recent years and it is hard for a newcomer to decide on the choice. Although I still managed to do it thanks to the information on this site https://innov8tiv.com/4-worthwhile-investing-apps-of-this-year-for-newbies-and-pros-4/ They talk about the most convenient for beginners and experienced mobile applications. I have generally no problems with their development. And in general the site has a lot of useful news on the subject of investing.
