Yes, Bitcoin cannot be controlled by the government or anyone else. but the government tries to keep information or even taxes from those who own Bitcoin. They get it from centralized exchanges in countries where Bitcoin ownership is legal. Centralized exchanges require all their users to carry out KYC verification. and the government continues to regulate every use of exchanges and ownership of crypto assets under the pretext of protecting their citizens.

The Bitcoins may not be hackable. However, the device you use and the wrong way to use your wallet can cause your Bitcoins to change hands without you knowing.
Avoid connecting your wallet to random websites. also, avoid looking at links you don't recognize. and if you keep or use a wallet that is connected to a device that you use every day, it's better to start separating it.
