Governments can discover you with your wallet address, but it can be a little difficult to prove it. Another way is they can find you with your cookie which the sites you visited. For that you should use VPN program and it can safe you from governments.

Totally agree with you,everyone thinks it's mega anonymous and it's not.!Calculate the specialists who have millions of dollars of the budget will not create a lot of work .So if someone wants to do illegal business through bitcoin then think twice!

But i do not think that currently there is any such way through which your government can discover your, and that is the reason that we called bitcoin as anonymous currency, which can hide your investment and your assets that you have in your wallet.

NO one can't determine that a particular bitcoins belongs to this man or this and neither can it be trace to another owner who payment has been made to. The best government can do is to trace from the books of exchange it was bought from.

It is only possible for the government to trace you when you have an account with crypto-currencies exchanges that requires KYC documents from you for verification, it will be more difficult to trace a person down who owns bitcoin if that person only uses hardware wallet to store his bitcoin and do transactions online without using any crypto-currencies exchange.

It's hard for the government to track you down if you own a bitcoin or altcoin, if btc is legitimate, then maybe the government will ask people to take part in bitcoin to create personal profiles on the individual and assignments. Translation must be declared

The govement will be able to track your bitcoins, if the anonymity ends on the exchanges, and after each of your trade you will receive a tax bill.

you can be trace via your public key or bitcoin address if they will search and follow it online but if you use a mixing service for your coins , then they cannot trace you directly.

other options to keep your transactions anonymous and safe is to use some privacy coins like monero .

But why would government tracked you? For what purpose?  you dont need to worry at all if you dont do anything illegal.

Government will only traced hackers and scammers.

Each bitcoin transaction is anonymous the only way to find out that you have hold of bitcoins is to view your wallet address right away. But they can only do this if you investigate them well.

So you should be careful of every action you have, And of course those who are close to you should say that you have hold of bitcoins.

I think there is only one way the government can track someone having a btc ,,, that is by tracing through the user's IP address btc,because of criptocurrency bitcoin, its bitcoin transactions run with the internet.
