Bitcoin does not provide anonymity. Please don't spread false information. With what's already going on with the surveillance state, your Bitcoin transactions can't be expected to remain private.

“The one major thing missing from Bitcoin and Litecoin being good money is fungibility”
“So if I, lets say bought like 10 Bitcoins on an exchange and deposit it to my wallet and want to pay someone for coffee or for whatever right, I want pay someone back $5 for lunch. If I send him $5 from those 10 Bitcoins then he knows that I have 10 Bitcoins or 10 thousand dollars in my wallet and he can track where that money came from and where I spend it next”
“It seems kind of silly that if I pay him $5 all of a sudden he has access to all my information about how much money I have, where I’m storing it, how I’m using it, and he can track where that money came from and where I spend it next.”
“Its not about buying drugs, it’s about when you are using money, you don’t want to have to decide which one of the coins to spend due to it having some history”
“It’s like if you take out your wallet to pay someone and you have to decide which one of the $20 dollar bills to use because one of the $20 bills is tied to more private information you don’t want anyone to know about.”

Those words are from Charlie Lee. If Bitcoin was miraculously fungible I think he would be one of the first people to know.
