Aside from economic collapse scenarios, many countries are in the process of eliminating physical cash and coins. Instead, everyone has an account that holds their money. You cannot purchase goods or services without access to government-based cryptocurrency. Even if the currency itself is still backed by faith in the government, you have to use this electronic system.

The result is multiple problems that could leave you in a situation where you have the money in the bank to pay your bills and purchase goods and services, yet you cannot do so.

These threats include:

Attacks Sponsored by Foreign Governments

These hacks usually affect the bank or primary clearinghouse rather than a specific person's account. You may be unable to purchase goods or services for hours or days. While this is inconvenient, it isn't as bad as a full collapse, where the banks close for good.

There's only so much you can do about this kind of hack other than make sure you can go two weeks without buying anything at any given time. It is also essential to keep a paper-based address book with phone numbers and account information so that you can contact utility companies or others who may be expecting payments from you while the bank or clearinghouse is down.

Let's say you can connect to Wi-Fi independently of the SIM Card. Your phone app may not work with Wi-Fi. This is why I recommend having an app on your phone that doesn't use the SIM card to dial out on Wi-Fi so that you can make the necessary calls.

Attacks Sponsored by Non-government Groups

If the hacker was able to steal money from your accounts, it could take weeks to years before you recover the money. In the short term, you will have to shut down credit cards and so on, then wait for new ones to come in the mail. You may also have to manage restoring devices and regaining access to your accounts.

Here again, make sure you can go at least 2 weeks without buying anything so that you can manage your basic necessities.
