Alternatively, consider crypto assets, such as Bitcoin or ether, which are not pegged to major national currencies. They are useful hedges and speculation vehicles, but you probably would not want to use them as your dominant means of purchase. If they can go up in value so rapidly, they can fall too, sometimes precipitously. That’s OK if you’re using crypto assets for a modest portion of your purchases. But it’s too risky to make them the bulk of your checking and savings accounts. The dollar, euro or, for that matter, the Mexican peso are not nearly so volatile.
