Also, bear in mind that control over one’s privacy isn’t entirely in the hands of the individual. When one user’s privacy is lost, that degrades the privacy of all other users. Through the process of elimination, which suggests a linear progression of privacy decay, every successfully deanonymized user can be discounted as a possible candidate when attempting to deanonymize the transactions of the remaining users. In other words, even if you take precautions to protect your privacy, there will be no crowd to blend into if others don't take precautions, too.
