If they are non-vbv bins you can do plenty of things with them like buy giftcards, liquids goods, illiquid goods, etc...
if not you can still do somethings but since you are new atm you can't really do much unless you know some 2ds websites where you can cash out those cards there's not much you can do.
I don't know if you already know the basics in carding but if not you gotta learn the basics first like proxys, anti detects browsers, fraud score, vbv and non-vbv bins, 2d and 3d secure websites, different cashout methods, etc...
And after your research you can decide what route would be the best for you and pursue this way
But for now i'd say keep your cards learn about those things i said in this thread and then you can see what you are going to do
