I saw that a person supposedly in the know on these things post that the FBI sent a back channel notification to vulnerable financial institutions stating that a group of Chinese hackers have penetrated a firewall on the system that controls ATMs and credit/debit card transactions. The FBI sent out a number of above-board warnings earlier this year that hackers and terrorist were targeting our infrastructure. Apparently the institutions affected are working to plug the leaks, but this guy said that you should have enough cash on hand to handle anything you need over the weekend just in case the leaks cannot be plugged. Nobody knows why this is being done. It could be just practice for the war with Taiwan or other reason. Who knows? Act on it or not. Your choice. Canada had similar things go on late in 2023.
Interesting. By coincidence, I replaced my on-hand cash just yesterday (firewood, yard sale stuff.) I don't worry about the Chinese as much as I do Friendly Fire, especially in an election yer.
