I went through something similar when I listed a skin on impulse and realized later it had a rare pattern that could’ve sold for double. After that, I wanted to actually understand how all the factors come together. One of the best sources I came across was https://dmarket.com/cs2-wiki/. It’s got everything—from basic terminology to in-depth breakdowns of what impacts value and how to trade safely. I keep going back to it whenever I feel unsure or need a quick refresher. It really helped me build confidence in my trades and avoid mistakes I used to make all the time.
