Cash will eventually cease. In the US, over 80% of all transactions are now cashless. Plus, the government cannot monitor cash transactions. That hinders their control, ability to track, and ability to tax. There are some obstacles still to cross, but they are all easy to implement.
The fedzilla cannot monitor cash transactions, plus some companies offer a cash discount. And with cash, you don’t go into debt. Whoo Hoo, good stuff.
