So what is the deal with agents in the end?
Are they foot soldiers or to they operate on the network virtually?
they bring money, for sure

manually bring money? is it safe?
Maybe they could establish some small offices around,where people could come and pick up the money?That would be easy way to sort that issue.
they gone say how it is secure, but in short way, agent must give some deposit amount of his money for start

so there is some vouching for the agent after all.
