TF2 Trading at 15
At 15, I made around £800 trading TF2 items. The strategy was two-pronged: scouting unpriced or mispriced items where the seller didn't know market value and buying them cheap, and running upgrade/downgrade arbitrage — converting between item tiers when the spread was wide enough. I tracked prices manually, watched demand shifts, and learned that most edge disappears fast once it's visible. The discipline was knowing when a trade thesis was wrong and cutting it, not averaging down on a bad buy.
