Im 24 and been investing for just one month

Hey guys, i been investing for the last month bb i started a new job and i wanted to protect my saves from the inflation. Im 24 and id like to have enough money to buy me a house at my 30/35 and still having investments. I use Trade Republic and a lot of the efts i see you usually talk about here are not avaliable on my bank.
