If there are multiple routes across multiple networks, but the user doesn't have a positive balance
on the network which the router initially suggested as the best (cheapest) route, then we are not returning
an error saying there are not enough balance, but instead try to suggest the route on the network where
the user has a positive balance even that's not the cheapest route (it should be the second cheapest route,
but if there are not enough balance on it we proceed with the third cheapest route and so on...).
