Dollars are still strong and able to purchase lots of cool stuff. Although crypto is making headway in eroding that position of supremacy. Crypto is starting to become the most powerful form of transactional medium, but it's not quite there yet.  

Dollar still works really well, but it is becoming diluted and people are losing faith in the dollar system.

Gold and silver are super solid for trade and barter, 1/10th ounce coins can be used to trade for food, supplies, energy or smokes in a time of need.

I would never refuse silver or gold in exchange for my products.
