I have a full-time job which allows me to fully pay my college debt, which is about 2000€/year, but not gonna lie it bothers me a lot the fact I have to pay so much. I have about 30 000€ I can invest. I am not sure whether it’s better to buy bonds so I get something like 1000€ in one year, or in ETFs which will require more time to get a good return, but it’ll be more. What do you suggest? Thank you.
