Bitcoin Anonymity

[awesomey]

I jumped on bitcoin because I've heard that it was anonymous. But after more reading I'm not so sure. Is it that all transactions can be monitored, traced, and/or viewed publicly? I mean ultimately if everything could be traced back to either you putting money in, or pulling money out... well that doesn't sound very anonymous to me at all!

So are bitcoins anonymous or not?

No one knows any identifying attributes that can be traced to you.

But wouldn't those bit coins have to have come from some initial transaction? Say for example:
- I use bitinstant buy some btc to put into my wallet by depositing cash through bank wire or whatever.
- Then lets say I spend those coins on a a product that is banned in my country, and some gov. agent recieves my btc and confiscates it.
 without knowing my identity, but looking in the bitcoin network, couldn't he ascertain that I had previously placed money from bitinstance into my wallet (assuming he know's bitinstants wallet address, order on bitinstant raid, get logs/interview, and identify my bank wire)? or if not bitinstant, find anyone in my transaction history whose wallet is known and get them to disclose (potentially) identifying information about me?

With some effort, bitcoin can be used in a rather anonymous way.  However, without effort it becomes rather easy to reduce your anonymity.

If I obtain all my bitcoin through either mining, or exchange with individuals who don't know my identity, and I use a new address for every transaction, and I am careful to never associate my identity with any of my bitcoin addresses, then I can be pretty anonymous using bitcoin.

However, if I provide identifying information to an exchange like Mt.Gox and use them for currency exchange then they can potentially provide that identifying information to entities who can then track my use of bitcoin.  If I use an address for a transaction with someone who can identify me, and then use that same address or other transactions in the future, then that person can provide my identity to entities who can then track my use of bitcoin.

Hmm, so even if one of my wallets were to be linked (potentially) to identifiable information, they'd be hard pressed to prove (without other evidence) that every address in-between was linked to me, and not some other joe turning it around and buying some government-hated product?

So the more hops the better for anonymity... hmm this currency is starting to sound like the internet

Yep, that's right.
Bitcoin is designed to be anonymous.

Bitcoin is designed to be anonymous.

Not true.

Bitcoin is meant to be pseudonymous.  There's a difference.

From the Bitcoin wiki:

While the Bitcoin technology can support strong anonymity, the current implementation is usually not very anonymous.

If it were anonymous, Goat's 400 BTC would still be gone:

 - http://bitcointalk.org/index.php?topic=113389.0  <-- Another example.

And if Bitcoins were anonymous, this wouldn't be possible:

Among other methods mentioned, I think one of the best ways to keep yourself anonymous is to use a mixing service to help sever any ties to previous bitcoin addresses.

You mean like TOR?
