This is why I can't take Bitcoin seriously. The privacy implications are insane.

Why is privacy a necessary property of a "serious" currency? Just because that's the precedent doesn't mean it's the 'right way'.

Because Bitcoin its only applicable use case is to buy drugs with. What's the point if it's without privacy?

What do you mean exactly? If you want, you can say which addresses are yours. If you don't: privacy!

Without running through a mixer, aren't one's transactions are vulnerable to being followed through the network of addresses back to the point of origin, and forward to the destination?

Depends on where you first entered the 'system' that makes you reveal your identity. For example, if you buy on localbitcoins in a face to face exchange without the need of identification, it wouldn't be feasible to track the Bitcoins to your real identity. Sovereign money to Bitcoin conversion is the spot where identities are revealed. Otherwise, it remains pseudonymous.

Traditional currency isn't really anonymous. Sure it is theoretically possible to do an anonymous 150 million dollar cash transaction in USD but in practical terms it's basically impossible without a great deal of money laundering. I believe by law in North America banks have to report any cash transactions >= 10k per 24 hour period to the government. Additionally every bill has a traceable serial number on it.

I wonder if it ever becomes viable to try to brute-force the private key of such a valuable address, rather than devoting the brute force power to mining.

Edit: got curious and found an answer: http://bitcoin.stackexchange.com/questions/2847/how-long-wou...

If I understand correctly, it's still not viable even if you tried your brute-forced keys on all addresses in the network.

Please stop with the privacy scaremongering. A lot of work is currently going into trustless mixing/anonymising services that will largely stop this type of tracking. (coinjoin/zerocoin) A lot of us are investing with the expectation true anonymous transactions eventually happen, because when they do Bitcoin will become even more valuable.

It's not scaremongering. Can you trust the mixing services?

Call it what it is, money laundering.

The question is will the Bitcoin Foundation put those add-ons into the Bitcoin protocol? I think they would be quite reluctant to do it at this point, as they are more concerned with establishing Bitcoin as a viable currency right now, that's not used just by Silk Road and its ilk.

I do think in the mid to long term Zerocoin or something similar should be added to Bitcoin to at least allow people the option to be anonymous if they want to be.

However, I'm also unsure if this should be done right now as governments are trying to decide what to do with Bitcoin. Perhaps it would be better to wait a couple more years, get Bitcoin more established into the mainstream, and adopted by banks and more companies, and then enable something like Zerocoin in the protocol, when it would be too late to stop Bitcoin. Although I'm not sure what the government's reaction towards Zerocoin would be then.

On the other hand, Bitcoin may be even harder to kill than file-sharing/torrenting, in which case maybe it won't matter if it's done now, as the government's action against it could be irrelevant.

cheez is hardly scaremongering. As it stands truly anonymous and private transactions on Bitcoin are apparently impossible. (I'm not a Bitcoin user so feel free to correct me.) I would say that you are the one who is doing whatever the opposite of scaremongering would be called (hope-mongering?).

> anonymous and private transactions

Something doesn't have to be private to be anonymous. So if you're happy with anonymous and public it's possible, but hard.

In theory yes, but as the linked blog-post shows, Bitcoin---in its current state anyway---likely isn't truly anonymous either (ostensibly due to its transactional records being public).
