yes, this is true but bitcoin is still pseudo-anonymous and it depends a lot on another factors

Basically true.. Bitcoin is pseudo-anonymous and it's already said in the article I posted here. When I read your previous post again and again, I got it better now, thanks

Disable change addresses. They are the worst when it comes to reveal your bitcoin addresses. Then, always, when you want to do a transaction, think about from which address to send. If you don't want that an address is revealed, maybe because you are invested in a scam company with it, then send the funds to an exchange. Every transaction to that exchange let you give a new address there. You don't want them all go the same address. Then you can send them back and you have fresh coins.

If you sent already from one of your addresses then think about that too. Maybe you don't want that one of the receivers of the transactions does know that you sent to the other service and so on.

Simply use your brain and decide which amount to send from which address.

But everytime you put money in an exchange the transaction is linked to some data of you, at least an IP and email address. Also, for the mixers you are trusting that they don't keep logs.. its centralized. Hopefully in the future there are better alternatives. It works for now tho and generally should give you a good level of anonymity if you want that.

Bitcoin is actually not anonymous, but it's pseudo-anonymous. If you send just random transactions then you are anonymous, but if you want to buy something from bitfinex then you are not.

in the latter you're not anon only because your bank account is linked with your account on bitfinex, not because of bitcoin itself, can be easily avoided by using localbitcoin or bitcointalk to purchase bitcoin

yes many websites require to verify your account by ID
I dont understand these websites that requires to verify you account so deep.
That is absurd for these kind of trades, it's just bitcoin lol

Somekindabitcoin has it right. There is a bitmixer.io extra fee of BTC0.0005 per extra address added.

Potential users of bitmixer.io should carefully read their instructions, and follow them!

Same with new users of blockchain.info's SharedCoin.

Yes i think maybe everything is tracked, as long as nobody will keep a look at your transaction.
But some stolen bitcoin still has not been seen anywhere.

Maybe the thieves used some kind of Bitcoin Mixer / Tumbler for example bitmixer.io. It's pretty much amazing service because you can split the amount to unlimited addresses with 12%, 8%, 30%, 5%, 5%, 40% of the original amount or any other %...
Fee is just 0.0005 per address.

Well the thief were to smart when they stole the money.
I remember the bter exchange when was hacked and around 7100 BTC were stolen
They used soemthing like this to disappear the money.
Btw the fee is nothing per address on bitmixer lol

Yes, there's 0.0005 BTC fee for every forward address. Please, don't spam here if you don't know how it is.

Absolutely spot-on, check walletexplorer.com out if you have doubts.

What is ths website about and how to use it? I don't understand what those numbers that are on the website means... can you please explain it to me?

It's exactly what it says - it correlates wallet addresses and transaction flows. For example, let's use DPR Seized Coins address, https://blockchain.info/address/1FfmbHfnpaZjKFvyi1okTjJJusN455paPH

https://www.walletexplorer.com/wallet/885d7317d7d3db17?from_address=1FfmbHfnpaZjKFvyi1okTjJJusN455paPH

At the top, (The latest tranasctions on that address), you can see dust inputs after the US Marshall Service moved the coins on 2014-06-12 - This site keeps track of wallets/sites who likely own them, so you can see some of the dust was sent from :

Bitfinex
BetVIP.com
(And others unknown to the site, obviously).

Try using one of your own BTC addresses, you may be surprised, especially if you gamble or use different exchanges.

I remember watching the Bitstamp hacked address using this, and you could clearly see the criminals emptying out the wallet and sending coins to everything from other exchanges, to DNM's, to other wallets etc etc... Pretty much proves bitcoin is not anonymous to me, at least without proper mixing anyhow.

I also look at like this - If this public site above can do that much sleuthing on the blockchain, just imagine what governments or independent researchers can do?! Tongue

Hope that helps. Wink

There's a couple of problems with the fact that Bitcoin isn't anonymous. First is the lack of privacy. Blockchain analysis can be done by anyone, and means there is no privacy. Glenn Greenwald does an excellent talk on Why Privacy Matters: http://www.ted.com/talks/glenn_greenwald_why_privacy_matters.

The second problem is the fact that, anyone can end up with tainted or blacklisted coins, even though they have never taken part in any illicit transaction. So we are expected to use a mixing service to try and get "good" coins? And the coins you receive after mixing, well some of them could be tainted too. So, try again? I'd imagine a large proportion of transactions with Bitcoin are illicit, so chances are you'll have some tainted coins yourself.

I'd rather use a crypto which provides the essential privacy we need at the protocol level. Monero does this. It's only a matter of time until people realise the importance of this.

To clear up some terminology:
nickname, nom-de-plume, pen-name are all pseudonyms. People have abbreviated pseudonym as 'nym' for a long time too.

In bitcoin, your addresses are kinda like books you've published under a pen-name because they can all probably be linked together with some sophisticated blockchain analysis.
Once any one of those is tied to a real id (you buy from a site and give a postal address for example), then the nym is (potentially) outed.
So bitcoin is described as pseudonymous.

If we make 10 different addresses and split the bitcoin to them and moving to an exchanger is this anonymity?
A good idea to me

It's not true 1:1 anonimity, it's just increased anonymity, to the point it's (as far as I know) imposible to know who the owner of the coins if after you withdraw them from the exchange, but if goverment or something asks the exchange for logs, they should know after that, but general public will not be able to know. For this to work 100% tho, when you withdraw the output address has to be shared with other transactions from other people, im not sure if this happens all the time. Someone should do a tutorial in how to get this right.

I see many transaction that on the left (input i think) has a lots of addressses and on the right lots of them.
Does this affect the anonymity ?
