Does the government know how much crypto I have?

I'm curious, does the government have any insight into the amount of cryptocurrency I currently hold? With the rise of digital assets, I'm concerned about my privacy and the potential for authorities to monitor my holdings. Do I need to disclose my crypto holdings to any regulatory bodies, or is my ownership of these assets kept private and confidential? It's essential for me to understand the legal landscape surrounding my crypto investments and ensure my financial privacy is protected.
