Is it possible to get 100% anonymous bitcoins?

[MUFC]

You personally can remain anon. For example nobody knows who satoshi really is but they can see a lot of his transactions but can't trace them to his real world identity. You can also use mixers to mask where your coins are going.

That is a very bad example. You can't use a person who hasn't used Bitcoin for years as a example. A person (if it is one) that did his best to hide his identity from the start. The average user does not fit this description. Someone who is actively using Bitcoin on a few services can not hide his identity. The services (i.e. ones that require ID) keep records of money transferred in and out, in addition to the addresses that you've used. A worse scenario would be if one of those services got hacked and all the information got leaked.

Because the ledger is transparent and permanent, one has to think ahead. If someone gets information in 2020, they can trace it all back to the begging easily (especially considering that there will be advanced tools by then).

I don't think it's a bad example. Satoshi is proof that you can do it. The average user doesn't want to remain a ghost but I'm sure there are many people on here or on the darknet that remain unknown in every or most aspects. If you want to remain anoymous from the start then I don't really think it's that difficult as long as you have a little knowledge on what you need to do. Use tor or proxies and do cash transactions or use exchanges that don't require ID and you shouldnt have much problems.

It is definitely possible to get pseudonym but not anonymity. You can try to reduce taint by using a mixer such as bitmixer.io. Even though they claim not to keep logs, they may very well be supplying the logs to the government. It is hard to trust anyone. Alternatively, you can also buy from a miner. It is ultimately one of the more secure ways provided that the miner do not reveal your identity to others. It is actually possible to track people using a mixer even though it would very much be significantly harder. To reduce this, delays are introduced in many mixers.

The only way to get anonymous Bitcoins 100% would be to mine them, because they are freshly minted and have no past transaction history.
The second tier of anonymity would be to get paid in Bitcoin directly (never due a 3rd party payment system such as Bitwage, Bitpay and whatnot)
The third tier would be an IRL exchange of Bitcoin for cash
Beyond this tier I think it's useless to talk about anonymity.

I read in the internet that send your coins to BTC-e and then withdraw BTC-e coins to a large trusted gambling site like PrimeDice.com or Just-Dice.com. Withdraw gambling site coins to blockchain.info. At this point your coins have over 85% chance of broken links to the original coins.

But I have a question - XAPO uses dynamic addresses each time to send and receive. So if we send coins to xapo and withdraw means is it going be completely anonymous or not?

Well but there will be recorded log of you buying BTC in BTC-e so it's not a 100% anonymous movement. I think the only way to do 100% anonymous buy of bitcoin is localbitcoin with a person for cash and hope the person is not some sort of undercover or whistleblower.

BTC-e don't require personal information but they could be recording your transactions and they might keep logs of it. Just-dice.com doesn't offer Bitcoin. Primedice is okay but still, they can keep logs.

Xapo requires some personal information for me (at least) to use it. Dynamic address are fine as long as it doesn't send the coins directly from your deposit to withdrawal address. Xapo is a registered business so there is a good chance that they need to comply with the regulations and release customer's informations.

I think most people think Bitcoin is anonymous, even if they they use Tor... but they might be surprised how much information is transmitted without you even knowing it.

You should watch this recent video for more information on the topic... https://www.youtube.com/watch?v=gd5NZvsyAfw

These agencies have very skilled people and resources to identify you, if they really want to do it. Just keep everything legal and you would be fine.

If you buy bitcoins for cash from a person you trust that will never reveal your identity (or you buy coins with a sock over your face so this person don't see your face while handing them cash) and you spend them online, let's say from public hot-spots or public Wi-Fi with watching that your real identity
 never gets connected to the certain address, let's say 1tazauaZS...

This is for me only way to stay anonymous, well at least anonymous with your real world identity since you will be always identifiable by your Bitcoin address.

In everything else I don't trust.

[Amph]

it would be very simple if you never exchange your coins, for dirty fiat money, even if they could track back you, address by address...

then how they can say that those addresses belong to you if you didn't use them to purchase anything and therefore your name does not appear to be connected with any of them? impossible

[CasioK]

another possible way I read somewhere on forum today is buy newly generated bitcoins from someone
like buy a complete new generated block of 25BTC from someone by paying them some premium, these coins don't have any transaction history

its not easy to solo mine a complete block, or find a guy who solo mine a complete block
most blocks are mined by pools and they divide that money to their miners

I don't think 100% anonymity is possible.
It's possible to reach 99% anonymity by either using self-mined blocks or cracked insecure private keys, operating from a public toilet seat in a crowded environment using their non-mandatory-registration wifi connection with a MAC address changed client booted from a live OS distribution, finally chaining the proxies after the wifi entry point.

Sometimes, you can legally crack private keys and take all the funds by solving puzzles. If you're seeking for legal anonymous coins to crack, follow this internal link. That's your chance  

I don't need 99% anonymity. This is why my best practice is to do the buying&selling through face-to-face meetings, then paying my VPN using VPN prior to every expiration, which still sustains me good amount of anonymity.

If the govs thinks that it's relevant, they'll just do a house search which is displeasing enough for making efforts avoiding. Some countries also have mandatory password disclosure laws which brings you in danger by possibly finding illegal data by chance after decrypting your storage. For example, you could get in big trouble if you possess data which was perfectly legal when you acquired it but was being outlawed by the govs after some laws got tightend, possibly leaving you in possession of illegal data without even knowing.

I don't know if this is 100% true, and might be considered off topic... But I'm pretty sure if you take btc and switch them out for another coin with more anonymity features like cryptonote currencies, such as monero, you can be anonymous that way... The only risk you have is if monero loses its value over time, and the fact you would have to find merchants who would accept xmr as well..

But then again I'm not quite positive about that as well, because shapeshift might keep logs of the addresses you used, etc.

This is off topic. You're talking about holding an altcoin. OP is asking about being able to use/transact Bitcoin 100% anonymously. P.S. Don't promote Monero here.

I don't think it's a bad example. Satoshi is proof that you can do it.

It is a bad example. Satoshi is a special status user (or group). You don't even know that he is a single person, and you try to make a example as he was a user. Stop calling out on him for reference to everything. 

I think most people think Bitcoin is anonymous, even if they they use Tor... but they might be surprised how much information is transmitted without you even knowing it.

Encrypted VPN(s) that do not keep logs are better in my opinion. Tor helps but it has it's own problems.

There was a project called Mint (currently on hold) from Blocktrail. Their plan was to sell a limited supply of coins directly from a miner.

I don't think 100% anonymity is possible.

It is not and it is not necessary. Nobody will invest a lot of money to track a random user without a good reason.

You need to convert your Bitcoin for dirty fiat money if you want to pay bills with your Bitcoin, and you can't do anything with your Bitcoin but small purchases that don't raise any alarms. You can't unfortunately buy a car or a house with Bitcoin and don't expect the IRS to knock on your door.
That's why a lot of people is holding. They don't know what to do with the BTC they make for example in here. They know they are limited to small purchases, or else you'll need to get it taxed..

Hello bitcointalk,
is it possible to stay (online) 100% anonymous with bitcoin?
I heard about bitcoin mixers but how can I see that it is really impossible for everyone to track the coins?
Read a couple things about the blockchain taint analysis but is there no other way to get the original origin?
Btw. I'm really sorry for my bad english it's not my mother tongue.

Possible with true solo mining.  This way, only you have 'new' coins since those coins are new to the network.

[RGBKey]

There are ways to track the bitcoins, but that doesn't mean that it can be easy at all. Don't reuse addresses, use mixers, don't tie addresses to real world information.

[l8orre]

you can to use JUMBLR:

https://bitcointalk.org/index.php?topic=1179305.msg12407691#msg12407691

https://nxtforum.org/nxtservices-releases/jumblr-decentralized-bitcoin-mixer-seeking-marketing-lead-and-also-gui-dev/msg193934/#msg193934

Currently there is no GUI, so the usage is still a bit cumbersome, but it works.

The funds remain 100% under your control at all times, and there is no central party involved.

JUMBLR operates on the SuperNET platform.

well that's is clear, buying big thing is out of question, no matter what you use to pay for thing like an house, it will be known by your gov/taxman

but i'm sure OP is talking about other type of thing to buy, or he want to hide his transfer of money

You just send your coins to XAPO account and again send back to your main account from XAPO. This means the transactions chain has broken right? Becasue they use dynamic ip to receive and send so difficult to trace back the transaction.
