The U.S. and their regulations/laws relating to crypto keeps getting stricter, i know there is the argument that they are doing this to combat money laundering, terrorism financing and other criminal transactions, but they are also eroding privacy as they want to know everything about people using crypto. This new law in summary means if you receive an amount greater than $10k, you must provide the name, address and SSN of the sender.
Needless to say that there are many instances that you may not have that information, and the article points that out, for example, in the case of miners or people who use p2p exchanges. It is clear the U.S. government do not want people to use crypto privately anymore, as they want people to only carry out tx's through centralized exchanges and services.
