It's all about random good skin with a slim probability, but you can
Typically you won’t find great skins unless you explore cases. But after playing long enough, you’ll accumulate many and can trade them for cash on Steam, which you can then use to purchase higher-tier skins. They don’t significantly enhance the game from my perspective, yet I usually sell all my items at year’s end and buy cheaper options during holiday sales.
It seems like you're questioning the value of each skin, suggesting they were worth very little to sell.
Do you need to purchase cases, or can we acquire them by playing sufficiently?
You encounter issues occasionally, yet purchasing keys is essential.
I once owned something that cost around €2.50, while most other items were under €0.10. But if you have sufficient funds (and also cards and other trinkets from other games), you can earn a few dollars each year. You typically get the cases or buy them cheaply, but the keys to open them must be purchased separately. Personally, I wouldn't consider it worthwhile because it's mostly cosmetic and doesn't significantly improve gameplay.
Those items definitely have value. Have you sold them or are you still using them?
