Vietnam is well known for its daily use of gold by all levels of society in all markets, from grocery shopping to buying building materials.
With stacking and bartering (payment with gold) being a common daily thing, will you be looking into ways to incorporate that into your plans, so as to help make life easier for everyone there?
i.e. Not have to carry bars of gold around.
I can see crypto being utilized there more so than in most places where fiat (paper currencies) are used, purely for its practicality.
