The Zeitcoin movement is a global association of people who are fighting for sustainable resources on our planet. Helping the needy, investing in innovative techniques and the protection of the environment are all part of that.

Furthermore, the Zeitcoin movement includes a encrypted decentralized payment method, which acts without oversight and control by banks or governments.
The units will be generated from interest on the balance and credited to each participant in the network – this method is called “Proof of Stake“. All you need is a digital “Wallet” and the will to make a difference.
The interest rate is 25% in the first year, 20% the second year, 15% in the third year. After that, the interest rate is consistently at 5%, until the total amount 99 billion units has been reached.
