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?

I don't think that there are any wallets that use a single address (except for paper wallets). People would have to register a new address every time they receive bitcoins, so I don't think it will ever happen.
