This is what happens when "GREED" is a dominant factor. This also happens when we relegate "EXPERTISE" and rely on emotions while gambling or making sports betting. In this case both the gambler and the betting agent are at fault.
1. The betting agent forgot that in business; never mix emotions with business (just like in crypto currency too)
2. The gambler forgot that with greed, you will lose all and earn nothing.
Finally, i think that the betting agent and gambler are probably individuals who have close ties; they will resolve their fights when the gambler wins a new bet and is able to afford a refund; and then move on with their lives until another crisis surfaces out of greed (Will happen definitely).
Greed have been the major factor that leads gamblers into this kind of situation and in this case, both the gambler and the agent are greedy in their different ways, because both of them are culprits in all this and for them to reach such an agreement and settle to bet in credits, it means that this is not first time this is happening and if truly so it then means that this will not also be the last time either because this is a Normal way of operating the business because their want to make a real sale by all means.
