Are you in favor to register your BTC Wallet address to trace transactions and impose taxed it? It is a big subject now amongst lawmakers to trace down income and transaction about bitcoins. This has become the talk of the people involved in digital currency lately. So, What do you think?

That is really the opposite of how bitcoin should work, it should somewhat be anonymous, But if governments would impose this I think we can't do anything about it.
We are still on a world where it is being regulated by governments.
I agree , for sure if the your country will fully welcome and formally legalize the cyrpto currency, the government will surely find ways on how to trace all the transaction for the sake of tax generation. I think that is one of the disadvantage when that time comes.
