Lol. Ethereum miners 've bought many equipment to make their farms. Average Ethereum mining farm costs 2k $ and give to you 5500 $ per year.
But how does it works in Lisk? Developers delegate spends 80-120 $ per year and receive about 14k $. Do you think that it's fair?
Not all delegates have guarantees to stay within 101 forever. Everyone can run as Delegate including you. Delegate can cost as much as you think including their previous hard works.
