I understand why people need to mix/rinse coins. I don't judge people, I just mind my own business, I'm not stupid though. I know the reasons why people do it.
Ok, do not be evasive... state your reasons why you think people need to tumble their coins. You have privacy with cash, why not Bitcoin? There are not always sinister reasons behind mixing of coins.
If you valued your privacy, you should do it to. Let's take a little example : You want to sign up with a new service, but you not certain if this service is farming for information on your spending habits
or if they collecting information for marketers. You could mix your coins and then hide your original stash, and then signup with the destination address. If you did not do that, these services can trace
how many coins you have and how regularly you spend it and even on what you are spending it. See.. where privacy is valuable?
