Stay on a Centralized exchange like binance until you have a good grasp of how crypto works. Don't move your coins to metamask or any other wallet unless you're sure you know what you're doing and some of the ways you can be rugged.
"not your keys not your crypto" is a common saying because centralized exchanges have been caught freezing assets, going under and losing money, but ultimately they're probably safer for your money that the wilderness of going on chain without proper security.
When it comes to coins. Dont get suckered in for new random alt coins that will never go anywhere. Don't listen to crypto YouTubers. Without exception, they have no idea what they are talking about.
I mean that - without exception, every single one I have seen is either misinformed or an obvious shill.
Stick to the basics. Put a small amount into ETH each month as it is leaps and bounds ahead of any other network. You can buy Bitcoin if you want, I personally don't see a future in it but that's a somewhat controversial take.
Most of the other hyped coins you will hear about are riding high on expectations of value from other investors, they are not really being used. Do a lot of research before investing into any of them. They are not going to 100x tomorrow (or ever) so don't worry about that. Take your time
