mining reward – How is the Bitcoin network of nodes different from the IOTA network?

I asked this question in the IOTA forum here:

Real incentives to execute a complete node?

One of the founders of IOTA Come-From-Beyond (Sergey Ivancheglo) responded with this comment:

"However, since IOTA does not charge fees and does not reward the node
operators, what are the plausible real incentives to run one? "-
How is the operator of the Bitcoin node rewarded? Answer my question and you
You will probably get the answer to your own question.

I'm curious how someone with knowledge about Bitcoin would answer this question and compare it? Can you answer this question about the incentives and viability of the IOTA network by asking the same question about Bitcoin?

What do you think about this?
