Happy new year everyone, I have just recently found out about investments in ETFs and Im complete newbie to all of it. Im 26, coming from Croatia with steady income and would want to make 300/400€ monthly auto investment until retirement. Im registered at trading 212 and would want to buy a safe ETF on which I dont need to check on regularly. From your experiences, do you think I should invest only in one ETF or to put few of them in a pie. I would also appreciate suggestions for which one to buy that can guarantee stability over the years. Actually I would appreciate any kind of suggestion! Im aware that everything is a risk but also is my bank. Thank you!
