Thanks for the response. I just read about Bitcoin mixer. It's an easy idea, but I guess its implementation is complicated. How much is the fee for it?

Do you think governments will forbid anonymous transactions? For example, by forcing exchanges not to accept them.

Coinjoin is very weak. Read about coinjoin sudoku.

Exchanges are nice but not necessary. There will always be variation between jurisdictions anyhow, and crypto is global.

Yup, I just read the following paragraph from http://www.coinjoinsudoku.com/advisory/

Executive Summary:

The SharedCoin mixing service provided by Blockchain.info offers only limited privacy to users due to weaknesses in its design. Bitcoin users should carefully consider their privacy requirements and evaluate other mixing services if they require serious privacy guarantees. A tool for analyzing SharedCoin and other CoinJoin-based mixing protocols will be released approximately two weeks following this advisory to allow SharedCoin users adequate time to protect their privacy.
