not so much rewards on masternode... 7000$ and receive 13$/day.. not so big, but better than nothing.. hopefully the price will go up.
What about staking? anyone know the potential rewards of staking? is there some formula to do for understand what we will receive as reward for staking in future?
4700$ yearly on 7000 is "not much"? Sounds like a tremendous ratio to me. Where would you get such returns in traditional investment vehicles?
Staking statistics will probably start to show after several weeks of Proof of Stake. Ask around then..
