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.
There is no way any people could track or manage to see our private transaction because bitcoin and other cryptocurrency works on a decentralized system that is powered by blockchain. Technically government could only support and control the market by manipulating the choice of the people to choose on the market but they could not hack or manage to steal one's identity or transaction on a given basis.
