Most people who try in-game item arbitrage quit in the first month. Not because the margins aren't there — they are — but because they're pricing off vibes instead of data.

Here's a real example: a CS2 case-hardened knife pattern was listing for $1,240 on one marketplace while comparable float/pattern combos were trading $1,652 on another. That's a $412 spread before fees. The trader who caught it wasn't lucky — they had a scanner watching float ranges and pattern indexes across markets 24/7, flagging spreads the second they opened up.

The 3 mistakes that kill new arbitrage traders:

1. Manual price-checking. By the time you've alt-tabbed between 3 marketplaces, the spread is gone. Scanners catch it in seconds.

2. No risk rules. Going all-in on one item category (skins, runes, gear) means one patch/update can wipe your capital. Diversify across 2-3 markets minimum.

3. Ignoring liquidity. A 40% margin item that takes 3 weeks to sell is worse than a 12% margin item that sells in a day. Velocity compounds.

We teach the full system — scanner setup, watchlists, buy/sell checklists, and a 30-day plan to scale past $5K/month — inside Loot Arbitrage Lab. Course is linked on our page if you want the structured version, but even just fixing these 3 mistakes will improve your flips this week.
