The fall of the US Dollar is imminent. We all know that every fiat currency has failed. The dollar will have the same fate. Now, the question becomes, "What are we going to use for money." What are the people going to accept?
Gold and Silver be good in a more localized use. Gold and silver have a history of being used as money. People will be willing to accept this. Especially when you are able to see and hold your metal. This also leads to that it is too heavy, clunky, and expensive to use in a more globe use. You would have fright ships going across oceans just filled with gold or silver. This will be seemed as a waste.
Cryptocurrency is a better option for the more advanced globalized market. Bitcoin does have its speed issues, but so do the credit card merchants. You have to remember that only one side of the transaction is completed when you swipe your card. It takes 1-2 business days for the buyer's bank to fund the merchants bank. Monaro and Ethereum definitely have faster speeds and Bitcoin can be used as a store of value. The downside of Cryptocurrency is that you need the internet. The Washington Post reports that only 47% of the world uses the internet. This would leave over half the world without blacked out.
Barter System is something I believe will be use temporarily while we figure out best form of money. The best is going to be something people will accept. For that transition period, that could be food, water, power, labor.
The question now becomes, what will you now for the time that we stop using the Dollar. You don't want to keep all your eggs in the same basket, but what eggs are you going to have and from what farm?
