Skins are meant to be aesthetic and fun and not an investment
You can buy any skin you love in valorant for less than 100 dollars but in CS certain skins cost 100000 dollars
Still
Im not gonna play any game for my whole life so I'd rather put the money into skins that I can get some return from as well.
I got some skins in CS for nearly 15$ (Operation pass) and now I have more than 200$ so I like that :)
