you get paid for utilizing your unused bandwidth
What we get for unused bandwidth?, Itera token or something like coin listing on exchange?
are using internet self?, or we have to buy bandwidth for sharing video or seling product?
For bandwidth sharing you will get ITR. Advertising will be paid in ITR too so there will be consistent demand for ITR on exchanges. Also Supernodes need to stake ITR so this token will be in high demand. we will be listing on exchange as soon as it is released.
