Bitcoin Forum

Hi guys, I read good things about this place so I thought I would join, question.... say I buy bitcoins from Coinbase and send it too my blockchain wallet... can coinbase find out who I sent my bitcoin to once it's in my blockchain wallet. do they have access to that or only access to where I sent it from if its coming from coinbase? thanks I like to keep my stuff private thats why I ask

If you want to stay private (or even if you don't, for that matter), do not use coinbase or blockchain for your transactions or storage.
They are virtual banks, they give you an account, but don't give you private keys, they control the coins.
They can impose spend limits, freeze your account, or even confiscate your balance.
They also ask for your ID, so you can't be anonymous, and all your transactions are tied to your name.
Use mobile or desktop wallet for transactions (e.g. Electrum, Mycelium), and paper wallets for storage.
If you don't want Big Brother to trace you, use a mix before sending to your wallet.
If you don't have sole and complete control over the private keys, you don't have bitcoin.

So to confirm, say right now I deposit on coinbase or Gemini, and I send this to my blockchain wallet.. okay so now I got Bitcoins in my blockchain wallet..if i send that to a different address can gemini or coinbase find out the address that i sent it to? or only they can find out the one from coinbase to blockchain.. thanks

If I send from Electrum or Mycelium   can it be traced?  and out of the two which is more preferable

i think tracking who sender bitcoin, and who the receive bitcoin is not easy as you think, im using xapo bitcoin wallet , of course i can't control my bitcoin, but it's not easy to someone track my Tx. the address of bitcoin can't give you more information like ip address, who am i etc.

::)

for truly untracable transaction, im recomended to using Zcash shielded transaction no people can trace where you get your zcash and where you send your zcash

With all due respect how sure are you of this, is there an article or anything I can read, I just live a very private life.

There is no problem with somebody knowing whom you sent your bitcoins if you are not doing any illicit activities then you should not be afraid of something. Anyway the person whom you sent your bitcoins will not be known except if somebody knows your bitcoin address and the owner of the address or the receiver. BUt if no one knows that information then nobody can know whom you sent your bitcoins since what will appear on blockchain is the transaction and the bitcoin address only.

yobit is a good site? can i deposit in canadian currency using visa if so whats the fee

Do you mean that if you buy a bitcoin from coinbase then send it blockchain. If you send the bitcoin to the other bitcoin address, the sender are no longer access the bitcoin that he sent. Only the receiver can access the bitcoin, control it and manage once he received it.

I thought that blockchain.info let you copy your private keys and export it to another wallet. At least that was the case when they were using non-HD framework.
This is not possible anymore with their new HD wallet?

If you want to trade altcoins better use Poloniex.

ya pretty much like im gonna buy off coinbase, send it to my blockchain wallet, then from blockchain send it elsewhere, I know that coinbase can find out where u sent your original bitcoins but can they find out from blockchain and where u send it to what if they looked up the old address

I want to make a comment about your post. Coinbase has the reputation of freezing accounts, blockchain.io is more like an HD wallet on the web. You can load your blockchain wallet using Electrum or MultibitHD by inputting your secret seed words as far as I know. The site itself does not control your coins. Please do not lump Coinbase and blockchain.io as the same type of service.

I'll be honest my friend used his coinbase for gambling and they closed his account

Two very important pieces of information...

1.  On this forum, if you get a response from someone that has an advertisement in the signature space of their post then there is an extremely good chance that they have no idea what they are talking about and are just making up a nonsense response to increase their post count.  Most of them get paid per post, so they are more interested in creating posts than actually learning and helping.  You've received 8 such responses in this thread so far and none of them have accurately answered your question.

2.  In response to the question of yours that I've quoted above...  ABSOLUTELY.  Coinbase or Gemini would be able to determine what address you sent those bitcoins to with 100% certainty.

Note that there are steps you can take to make it much more difficult for them to determine what final address you intend the bitcoins to go to, but simply sending to a wallet and then sending from there will not hide where you sent them. It doesn't matter what wallet you use (blockchain.info, Electrum, Multibit, Bitcoin Core, Armory, Mycellium, etc).  The result is the same.  Send to one address, then send from there to another addresss, and it will always be possible for the person that sent to you to know what address you sent to.

I'll be honest I'm using bitcoins to play poker online pretty much, I know that coinbase doesn't allow you to send bitcoins to poker sites, so if i buy bitcoins off coinbase and send it to my blockchain wallet, and from blockchain to the poker site can coinbase still find out or they only know the one transaction from coinbase to blockchain

They can determine what address you send to when you fund the poker site if you use the bitcoins that you sent from coinbase to blockchain.info.

Whether or not they can tell if it was a gambling site depends on which site you sent to and how much information about their bitcoin addresses that site makes public or available to coinbase.

Only coinbase employees know if coinbase will try to trace your transaction from blockchain.info, but if they do attempt it, then they will definitely be able to tell what address you sent to. It's really pretty easy to do.

so what advice would u give me then?
 I been using coinbase to deposit i send it to blockchain from blockchain to acr, for about 8 months and nothing. but when i first opened account with coinbase i sent it to the poker site and they warned me

Blockchain.info doesn't ask for ID as far I know(they never asked for me) and I think they let you make a backup of their private keys, as most online wallets do. Of course they have all the data about you, your IP, when you logged, maybe data about your browser and other stuff, so they are far from being anonymous

Also use a desktop wallet won't guarantee anonymity, they still will have the IP data and all transaction story.


Also of course Coinbase can see to what address you sent your balance and can use blockchain analysis to try and determine who is the owner of the address.

This is why we use Mixer services like the one in my signature. You send your coins through these mixer services and it would become very difficult for anyone to follow the coins. < not impossible, but not accessible to the average Joe > They would have to approach the courts to issue a subpoena to get that information.

We do not have to be involved with illegal actions to use these mixer services, but it just adds a extra level of financial privacy that Bitcoin lack as a default feature. < Bitcoin is Pseudo anonymous >

do i have to pay for it?

Haha, bold statement. What if there was a website that would tell everyone the balance of your bank account if you entered in a public code / number? Would that make you feel "OK"? Would that be "no problem"?

I doubt it.

Obviously, they are in a business and there main purpose to operate is to have a profit.

To buy Bitcoin from Coinbase, you have to verify your identity with some from of government identification. This contradicts the fact that you said you live a private life. However, there are barely any websites that will allow you to buy Bitcoin without identity verification. If you send Bitcoin to you blockchain wallet and then into a gambling site, then nothing will happen at all. You will be able to use the coins however you want. Although, I don't recommend using Coinbase or blockchain to store your Bitcoin because they aren't very safe. A software wallet like electrum would be better.

Yes, they typically charge a couple of percent.
If you want the coins for gambling (which is a bad idea in the first place, an addicting waste of time and money), it is probably not worth worrying about getting traced.
Coinbase would probably not press charges or take anything to court, as it is not unusual for people to use bitcoin for gambling.
If you gamble directly off Coinbase, they would just freeze your account, if you take the coins out first, they are out of their control.
I believe the reason why Coinbase bans gambling is because they cover transaction fees for withdrawal, and gambling websites usually cause a high transaction volume, which Coinbase would have to pay for if they let you gamble.

OK, I did not know that blockchain.info let you have the keys, my bad, sorry about that.
The question referenced in your post did not exist at the time of my first post, did you expect me to predict it?
The importance of controlling your own keys is well known, as users of mtgox found out the hard way.
Finally, the part about using a mix is standard procedure for anonymization.
What part of my post is spam?
Or is my post the one exception that is not spam?
Please do not make sweeping statements about signatures implying spam.

No.  I expected you to answer the question that the OP had already asked.


The OP didn't ask about controlling keys.


And yet it doesn't answer the OP question.


The OP asked:
"can coinbase find out who I sent my bitcoin to once it's in my blockchain wallet?"
"do they have access to that or only access to where I sent it from if its coming from coinbase?"

Please point out to me where you answered this question.  Where did you tell the OP that coinbase would be able to where he sent the bitcoins from blockchain.info.  Your mixer advice might have been useful if the OP understood that coinbase could trace the transaction, but since he didn't know that he had no way of knowing that he'd need to use a mixer.

Furthermore, you made reference to Electrum and Mycellium, which only further added to the confusion (since the OP didn't ask about alternative wallets).  The OP ended up thinking that you were implying that he could avoid having his transaction traced if he used one of those wallets, as can be seen by his response:
"If I send from Electrum or Mycelium can it be traced?  and out of the two which is more preferable".

I live a private life to the people I don't know but I don't have a problem putting my info on regulated sites, and how do u know that if i send to blockchain using coinbase then from blockchain to the poker site that coinbase cant find out people are giving me different answers so whats the real one.. Someone that actually knows this for a fact, or can show me an article that is a long time member here i appreciate that as some say yes some say no thanks.

The Bitcoin Blockchain is public. Let's just take Blockchain.info as a wallet just like multibit, electrum etc.

Addresses can be connected to several services depending if the address sends the coins to a known wallet of that service. This can be done by analysing the transactions of that address. For example,
A is a known address of Primedice.com
B is your deposit address to Primedice
C is your Blockchain.info wallet
D is your Coinbase address.

This is how a transaction of yours would look like: D->C->B->A. Although Coinbase can't accurately determine if you used Primedice, they wouldn't want to take any chances and would probably suspend your account if you do this over and over again.

If you really treasure your coinbase account, use a mixer.

are there any free mixers?

Or try to avoid using Coinbase. If they want and intend to limit how you use a decentralized, censorship resistant currency by trying to censor you by using it freely then that service should be avoided and closed down. Coinbase is against the Bitcoin ethos. They have sacrificed freedom for a little image or facade of "legitimacy".

I think this was a easy answer, and Google would have helped you, any way welcome here, yes you can find all your Bitcoin query answered here. Op Coinbase.com and blockchain are different, and they have no mechanism what so ever to find out who send to know. All our money is send to a address not to a name. And even if someone finds your address how is he going to figure it is you. So you need not worry about your privacy ever for transactions.

Obviously coin base will have record of everything. you can easily convert your btc into any fiat currency using coin base
Bitpay is  also another good option
Usually i make transactions using bitpay.
For me , gaming is my first preference .
And if your call your self a gamer , you should know what counter strike is ,
So i can buy everything related to that using bitcoins.
