Should I invest if I’m 13 and have around $150–700 saved?

Hey everyone, I’m 13 years old and I’ve been trying to save some money little by little. Right now I can put together anywhere between $150 and $700 as starting capital. I don’t really know much about investing yet, but I don’t want to waste this chance.

My question is: ???? What’s the smartest way to invest it so it either grows slowly over time or at least stays safe instead of losing value?

Any advice for someone my age who’s just starting out would mean a lot. Thanks!
