WHERE CREDITS COME FROM, AND WHERE THEY GO

New credits enter the game through exactly three doors — the 5,000 signup grant, the +100 daily login, and contest payouts. They leave through exactly two — the 15% rake and the 5% seller fee. No other faucet, no other drain.

That is why the economy holds its shape, and why the ledger balances: every manager's balance summed equals every credit ever granted, won or sold, minus every credit ever spent.
