I bought it for 7 keys and 15 ref.

Luckily this trade was made two days before the Market Crash... and the hat hasn't dropped in price after that event.

I traded for 26 days, I made 338 trades in total and my final backpack value is 372.88 ref.

This means that I made 13 trades per day on average, making around 1.11 ref per trade.

If you have any questions about this challenge feel free to ask, I might make a raffle soon explaining in detail what I did to make profit...
