"Two-fold. First, find something people will pay for here - partially mooching off of your portal system income for a bit, then using that to pay for something else I could do that would make money and saying you did it, or something. Once that's set up, I find something to convert my currency to this one. Bricks of gold is a method, but they're heavy. I might buy expensive jewelry and try selling those, if it seems like those would have a good return value."
