If time is the main factor, then buying is definitely the quicker way. That said, trading can sometimes help you get rare skins at better deals if you’re patient. The good news is you can actually combine both approaches using sites like https://dmarket.com/ingame-items/item-list/csgo-skins
. The marketplace lets you instantly purchase what you want, but also gives you the option to exchange items with other players when you feel like experimenting. It makes the whole experience flexible – you don’t get locked into just one style of collecting. For someone who doesn’t want to spend endless hours negotiating, having that dual option is the most convenient way to build a collection.
