Just a little story: You know running a node does not give you any block reward or fee, but as the market depends on psychical differences beween two choices, and the cost is low, some people run nodes anyway, and the reason is the psychical profit.
I had the opportunity to talk about bitcoin today, and I mentioned the number of nodes, the purpose of nodes, and that I run one of them.
- So you are one in 6000 of people running nodes?
- Yes.
- In the world?
- Yes.
Low profile bragging.
