I have never used bitcoin mixer services (sooner or later, each of the signature campaigns participants will be visited by this thought) and in this regard, I have no idea how this service works. I'm not interested in "send BTC to this address", "receive BTC to another address" (I'm sure this info is on the each mixer website), but questions about collection of personal information by service providers matter to me.

In this topic , we are discuss the collection of information about users by hardware wallet applications. New points of view and comments will always be welcome here, because the more complete information we have, the more objectively can assess the situation.

I believe that when it comes to privacy and anonymity, you can't trust anyone at all. So what kind of information can a bitcoin mixer service get?

Next, I will voice hypothetical vulnerabilities from the point of view of a person who has NOT used mixer service, but is concerned about what information the bitcoin mixer can get. Please correct me or supplement if I'm wrong and I hope you answer the questions I'm looking for answers to.

1) Mixer knows BTC address from which you send and knows the address to which you receive. Is information about the connection of the sending address with the receiving address saved? If this info is stored on their server, having access to this info, you can unravel the entire chain of transactions?

2) If the mixing service provider is a website, then it can get various information, such as an IP address and location? What can the mixer learn about its customers in this way?

3) What information about users can generally be stored on bitcoin mixing service servers? If attackers / hackers get access to them, then this can be used to the detriment of users, right?

4) How can minimize the collection of personal information by mixers?

5) What other weaknesses and vulnerabilities are there in the scheme "your address 1 - mixer - your address 2"?

I may have more questions as I learn more about mixers.
