New to wallets and confused as what to do

Hi,

Pretty new to the whole wallet and exchange process. I started on the apps like coinbase where its all very easy to deposit and buy sell swap etc within the app. You can see how your assets are doing etc and so having bought some tokens and they are now in my wallet are they best just left in there or what to do with them?

I have the tokens in my wallet on metamask but gaining info on things such as how much was the coin when i purchased it etc so i can see what im either making or loosing? hope this makes sence.

Thanks
