Once you have your wallet open for 24 hours, your coins starts staking.
That means they start compiting with other coins to be the ones winning the newly created coins.
As it works in PoW, if you have 1% of the mining power you will win 1% of the mined coins. Same is in PoS.
what if i get a connection lost for example? so the 24 hours starts again from 0?
