The game has two currencies. Hard currency (Trophies) that are mainly bought with real money and soft currency (Gold) which are found in game. It is a fairly standard practice for those familiar with Free-2-Play (F2P) games. It was difficult to balance things so paying players and free players could compete on level footing but after three years I feel I've found a nice balance and if judging from player feedback the majority also feels the same.

The game's forum uses advertising but the income is negligible, maybe around $10 per month. This is likely due to the fact that it is the same eyeballs looking at the ads and it is not a high traffic forum.
