Diversification

The money will be plentiful.

Economic conditions on earth isn't all that important. When
economies go down a lot, investors go after precious metals which
we'll have an abundance of.. and control of its supply.

Direct Dollar to Yen and Yen to dollar can be accomplished referring
to current monetary exchange rates/tables.

Our first "money" may be in the form of tokens (like bus tokens?).
Later, we make our own monetary system. But we can relax a little
knowing we have precious metals.

On earth, we have manufacturers, wholesalers, and distributors we
deal with. We can sell retail too if we want.

I don't think there will be a shortage of money. No. Not at all.
