I would suggest an increasing exchange rate. The first GC you gain costs R$50k. Each subsequent GC costs R$1k more. So if you want 100GC, you pay R$149k for the last one which adds up to R$9,950k in total. The amount of GC you exchange resets each update, so in the next update the rate goes back to R$50k. So if you exchange all your R$ in one go you get a worse deal than if you drip-feed it gradually.

Also the strategy regarding the maanger would get interesting as once the rate goes over about R$150-200k the manager stops being worth it (unless it's free).
