can anyone trace any relation between two Adress .

[pawanjain]

Let us consider I am using HD wallet of myscellium or blockchain ( new version ) .
Now , if I will use mainly two adress of my wallet regularly .
then is it possible to give or find relation between those two ( it is to be noticed that I will never made transaction between these two adress , mean to each other )

I think it's not possible to trace them, because they have diffrent block and private key. You can not trace, unless you do transaction each other

Complete nonsense.

Please don't answer questions in the "Technical Discussion" sub-forum if you are just going to make up what ever you want. Newbies might not realize that you are just trying to increase your post count for your advertiser, and might accidentally believe what you say.

That really depends on the wallet you use, how you use it, and how much you want to hide the connection between the addresses.

Most wallets will occasionally simultaneously spend bitcoins that were received at both addresses when you create a transaction to send some bitcoins.  This transaction can then be traced back to see what addresses the bitcoins were previously received at.  Anyone doing this analysis will therefore have a strong indication that a single entity has access to BOTH private keys (which in your case means the addresses both belong to a single person, you).

With a lot of care, this can be avoided by using coin control.  Another way to avoid it is to use 2 separate wallets.

Note that it really doesn't make sense to re-use addresses.  An address should be used ONCE, and then never used again.  Too many people think of a bitcoin address as an "account number".  It isn't. And it isn't intended to be.  A bitcoin address is more like an invoice number. It is a way to determine who send you a payment and when.  Invoice numbers certainly could be re-used, but why would you? It would just make a mess of your payment tracking and wouldn't benefit you in any way.

Re-using bitcoin addresses reduces your anonymity and privacy, reduces the anonymity and privacy of the people you transact with, and slightly reduces your security.

Lite wallets all transmit a list of their addresses (or some equivalent) to the servers they use to get data about the network. Doing so obviously links your addresses together.  If you're running a full node this isn't an issue.

[DannyHamilton]

If you're running a full node this isn't an issue.

I agree that the transmitting a list of addresses isn't an issue.

But the use of multiple transaction inputs in a single transaction still makes it possible guess with a reasonable level of accuracy that the entity that provided a Txin-script (scriptSig) for one of the inputs is very likely to have provided the Txin-script (scriptSig) for all of the inputs.

This may be the best answer, now if you want some tips on how to manage your addresses in order not be traced back just use these :
- How to import private keys
- Address generator

With these you will be able to manage addresses, or if it is too complicated you can use coin controle or a bitcoin daemon to manage the coins, it is the same as coin controle, but with deeper controle, and without GUI.

I think what fikihafana means is that you cannot find a mathematical relation between the public keys (which are published when spending from the address) caused by them coming from the same HD seed. This is indeed the case, but may not answer the exact question that OP is asking (questions are often subject to interpretation).

It's mean Re-using our bitcoin address can put our privacy and security on danger situation?
If I still want to re-using my bitcoin address any other way to still keep anonymity, or people still can't trace my identy?

Absolutely.  You give up a lot of privacy if you re-use addresses.

and security?

Only very slightly, not an amount to really be concerned about.  But why give up any security when you can maintain higher security by simply using a new address for every transaction?

If I still want to re-using my bitcoin address

That's a bad idea.  Why would you want to do that.

any other way to still keep anonymity, or people still can't trace my identy?

Don't use bitcoin.

If you use such addresses very often like you are claiming and if these addresses are part of the same HD wallet, Mycellium,Electrum or Multibit any wallet explorer website like this one walletexplorer.com will show to anyone searching for them that they are part of the same wallet therefore linking those to a single user.

Those sites don't know about the HD wallets. They don't do any linking like that related to an HD wallet. Rather they spend link addresses, meaning that you used the same addresses as inputs in a transaction. This works for addresses in any wallet, not just HD wallets.

Thanks. I didn't know that, now I am realizing why my Ledger hardware wallet is showing 2-3 up to 6 addresses as part of same wallet in that site, because I have used up to 6 addresses as input in a transaction. I should try to be more careful from now on. I learned something valuable for the privacy of my ledger HW.1 today , thanks again @achow101 .
