Bitcoin advice for beginner

Hi everyone! :) I invested my first $100 in bitcoin a couple of weeks ago when it cost less. I have about another NZ$1000 that I would like to invest. I’m not sure if this is the type of page where it’s okay to ask for advice. But if so I was wondering if I’m best investing this now or waiting for a bit?

Thanks in advance and TBH I would love any tips or advice anyone can offer to someone starting their bitcoin journey.
