I wonder Masterbit will have PoS in the future or only PoW and Masternode?
PoS is good choice because it allows small investors, who don't have rigs and don't have enough money to buy masternodes still have opportunities to get passive earnings from staking their coins.
Forgive me, could you please to explain for me how to earn passive earnings from staking?
Pos stands for Proof of Stake, which means that you can validate a block transaction according on the amount of coins you holds. So that you will get rewarded with coins. The more you hold, the more rewards you have.
