Anyone can trace your wallet to know your balance if they know your address, whales and big investors can be targeted and trace down due to the large holdings in bitcoin and so on.
Firstly, why make your wallet address public? If you have any BTC address that has gone public, do not reuse for your holding. Our identities are not crested in our wallet address, if you don't make your address known to people, it's always a mystery to who owns whatever amount in holding.
And if we say we adapt full privacy by using bitcoin mixers the government still has an issue with it. The current regulation has a soft spot for mixers but I wont forget how they labelled them to be tools that supports money laundering and embezzlement.
TO EVERYONE, HOW CAN WE CREATE A BALANCE BETWEEN TRANSPARENCY AND PRIVACY IN BITCOIN?
This is similar to a thread i created not long ago
Public wallets & personal wallets coverage.. It covers about privacy and exposure of address, if it affects our identity.
