Two Coins, One Economy
Your game has one problem that looks like a virtue: everyone can earn everything for free if they grind long enough. So the players who'd pay decide they don't have to, and the players who won't pay anyway were never your revenue. A single currency forces you to choose between a dead paywall and a broken game. The fix is older than mobile — run two coins.
Soft currency is the stuff of daily play. You earn it by clearing levels, watching a rewarded ad, logging in, finishing a quest. It powers the loop. Hard currency is scarce — dropped sparingly, bought with real money, and spent only on the things that matter: the premium skin, the season pass, the shortcut that saves a week of grind. Most players never buy it. The few who do keep the lights on.
Why the split works
When both coins exist, the free player still progresses on soft currency and never hits a wall that only cash opens. That's what keeps them from quitting. The paying player spends hard currency to skip the wait, not to win the game — so the game stays fair, and the spend feels like a tip for time, not a toll for progress.
A single currency can't do that. Price it cheap and whales ignore it; price it dear and the free crowd stalls and leaves.
| Soft currency | Hard currency | |
|---|---|---|
| Who gets it | everyone, by playing | few, by paying or rare drops |
| What it buys | the loop, the daily stuff | premium, scarce, time-skip |
| Your risk if mis-set | inflation, nothing feels earned | paywall rage, churn |
| The lever | drop rate, sink balance | price, scarcity |
The inflation trap
Soft currency rots if you're not careful. Hand out too much and prices mean nothing; the store becomes a museum. The cure is a sink — something players always want to spend soft on that scales with them, so the coin keeps moving instead of piling up. Get the sink wrong and your economy either deflates (players hoard) or inflates (players shrug). Neither is a disaster, but both quietly bleed retention.
Hard currency's danger is the opposite: make it too easy to earn free and you've built a paywall nobody respects.
Where teams get it wrong
The mistake is tying hard currency to power. The moment a paying player can buy a win, the free majority smells pay-to-win and the reviews turn. Keep hard currency for cosmetics, convenience, and pace — never for a stat that beats a non-spender in a fair fight. That single rule is why the dual-coin model outlives every "one currency, one price" experiment that came before it.
On a runtime that leaves the economy to you, the split is yours to draw — and the balance is the whole game.
