You can earn 3%
3% of what?
Thanks!
Let's assume you have 1000 Block in your wallet
staking interest is 3% p.a (per annum)
1000 BLOCK * 0.03 = 30 BLOCK interest
prerequesite: the coins must not move from your wallet, wallet is unlocked for staking;
When you keep your coins in your wallet, you support the network. Hence you get rewarded (PoS / Proof of Staking).
Always based on the amount you actually have. The more coins, the higher the reward:
Amount of coins * 0.03 = your reward / year
Thanks! Sounds good!
