There is another interesting phenomenon that is quite common in crypto economies. Often agents with perverse intentions (e.g. ICO scammers) compete for attention and disseminate information/misinformation in order to exploit trust. This also takes advantage of the information diffusion characteristics of networks, and can be analyzed using epidemic diffusion models \cite{Lawyer_2015} ( as one can imagine, the recovery rate of a node might be low because trust is not only scarce but fragile) , or using game theory-based models \cite{Aymanns_2017}.
