In five to ten years a crisp, mint condition 50 or 100 dollar bill from the ‘late 1900’s’ will be a collector’s item. No one will be paying for anything with paper bills or coins. No one. It’s not just that we will be using credit cards and bank cards instead of cash, there won’t be any form of money that won’t be digital.

The Canadian and American dollar, and currencies from all over the world, will be digital cryptocurrencies. They won’t be like Bitcoin where every account address is public. When you pay, no one will be able to look into your account, but the money will be verified as real at the point of transaction. You will be able to instantly change currencies from one country’s currency to another, without a bank. You will also be able switch to another cryptocurrency or Visa, or MasterCard, or some form of smart contract IOU, that is staked against something you own (at a pre-determined interest rate).

Paper money will be nothing more than collectables like Magic the Gathering or Pokémon cards that are no longer printed.

It might seem crazy to think this will happen as soon as 5 years from now, but North America won’t be first. There are countries with incredible inflation that need to print larger and larger bills, making smaller bills useless. In countries like this, the cost of printing the money is hardly worth the effort. Imagine having to carry around seven to ten $50,000 bills to buy a loaf of bread! These economies will move to digital first.

But then the transition will grow exponentially. Within 10 years every nation will have a digital currency and paper money will be a thing of the past. Have any mint condition bills and coins? Keep them, they will be worth a lot more than face value for your grandchildren.
