The skin economy in CS2 is actually pretty complex and interesting once you understand it. Rarity is definitely a big factor, but there's also float values, sticker placements, and market trends to consider. Some skins become expensive because they're discontinued or from old cases that aren't opened much anymore. What really helped me understand the whole system was reading guides about https://dmarket.com/cs2-wiki/ which explains everything from basic skin grades to advanced trading strategies. You'll learn about things like StatTrak versions, wear patterns, and why certain AK-47 or AWP skins command such high prices. Understanding the market can actually help you make better decisions about which skins to buy or trade
