First of all, nice to have you here bro!
You have to know that there are a lot of coins, some of them are good, some of them, are bad( scams, pump and dump for profit etc ).. you gotta be careful in what coin you invest; the main thing is, when you create your portofolio, invest in as many coins as you can, not just in one.
Read about the project, read about the coin which you want to buy, read read read because information is power.
