Choose an amount that your community can contribute regularly. As a guideline, we recommend CHF 5 / 10 / 20 or EUR 4 / 8 / 16. It is important that both the amount and the promised reward feel right for everyone involved.
The lowest amount you can choose is CHF 4 / EUR 4. This minimum also applies to the free amount that is available to your backers. There is no upper limit for the free amount. You never know!
