staking is like playing lottery, the more loose (coins) you have, the higher the chance to get something.
it depends on the network weight and your weight. if the network weight increases, your chance of getting something decreases...
Calculate the needed balance:
To earn a 0.5 BRO reward every week calculate network weight / 5040 blocks per week
To earn a 0.5 BRO reward every day calculate network weight / 720 blocks per day
To earn a 0.5 BRO reward every hour calculate network weight / 30 blocks per hour
network weight changes... the ppl who have more coins get the Block and the reward ;/
masternode is more profitable at the moment..
