just brought Bitcoin for the first time, is there anything I should look out for?

i’m not gonna lie, i dont have a clue how crypto works but my boyfriend keeps telling me to get bitcoin so i did. is there anything im supposed to keep an eye out for and is it ok to only buy monthly? he’s refusing to explain anything to me and this subreddit is all about Bitcoin so i thought it was worth a shot asking via /r/Bitcoin https://bit.ly/3hDYK7k
