I don`t think that any govenment officials can track and steal your crypto currencies,if you store them on a decentralized wallet and you keep your private keys in a safe place.The Vietnamese communist governments might be really scary,but they can`t find your crypto.The european govenments aren`t that scary,they will never try to rob someone`s financial assets.
the government will never steal your crypto but know they can track your crypto transactions and it is good because of the illegal use of crypto. I really appreciate that now it is traceable and criminals cannot use their crypto freely for their illegal activities. But it is fact that no government is scare about crypto, because many government have legalized bitcoin and now they are making rules for crypto investment.
They can track it as long as you are using local centralized exchanges to withdraw or trade your crypto into fiat most of them required KYC to do that function, as long as you are not using nor submitting anything to identify yourself they just have the transparency of your transaction but not the owner of that wallet unless you've posted your wallet address somewhere on your social media accounts or any platforms that indicates your full name.
