These types of nomads, usually do not need/use too much of money as we know it. For them money means more barter with goods that are scarce in their life (they cannot produce themselves): cigarettes, salt, sugar, flour, moonshine, tools (knifes, axe).

I remember once, I was hiking long time some mountains and I encounter a nomad family with sheeps. For a good long knife and a bottle of strong moonshine I had, they were giving me all meat I could carry, cheese, milk, shelter and a lot of love and stories. I offered money, but they don't even look at them, were like, wtf you are giving me these, I have no use for them.
