Staking starts after holding in your Wallet for 20 days

Small amounts can take longer to stake , up to 30 days.
(Someone correct me if the Max stake time is longer than 30 days)

Interest on Proof of Stake:
Year 1: 25% | Year 2: 20% | Year 3: 15% | Year 4 and ongoing: 5%
4 confirmations per transaction means fast 2 mins confirmations
50 confirmations per ZEIT blocks
