IF being a top 50 witness was that easy wouldn't everyone be doing it?? Im not sure that being a witness is about creating a future, its more helping in a present tense and helping maintain the network....
I think it takes effort, time, money and knowledge to do these things, I'm willing to support and not expect someone to pay or reward me for it.
I own a mining company... I process the blockchain for the coins we mine. Do I somehow owe the communities of the people I mine coins for some sort of reward because I am helping maintain their network?
