When you say "my address" (not plural), I wonder if you are aware of the fact that you can have as many different addresses as you like? Completely unlinked and unrelated to eachother?
How inconvenient, giving out new addresses for every transaction every time. I can picture a lot of mistaken transactions due to this. Do people who pay me regularly for my services have to contact me each month for a new address?
Furthermore, even if you do send money from an address that your wife knows about, for example to a porn shop or violent cult, exactly how will she (or anyone) know that the receiving address is actually a porn shop or violent cult?
Do you think businesses will keep changing their deposit addresses everyday, i have already seen people tagging Mt Gox, Coinbase, Poloniex addresses
Even if you or my wife or my boss or anyone knows that the sending address was mine, then what?
Lol, are we really talking about this?
Why even wear clothes then? Walk naked, the what?
