More or less. As a delegate, you get 15 LSK(at least that's the last number I remember) every 17 minutes, plus transaction/other fees. So it's pretty much fixed. Specs don't really play a role(as long as the server is capable of fulfilling the task), uptime obviously does.
Thnx for the info! So basicly this would mean that daily around 128k of Lisk will be forged? It would be 46 million Lisk a year so i guess i made some math mistake?
What is the benefit of having more servers? Is it just to be sure that you have 100% uptime as a delegate or it can bring you more Lisk?
