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?
It'll be impossible to verify whether this data is stored by a mixer or not. Most say they won't keep logs or will only keep them for a certain amount of time (chipmixer is a week unless you destroy your session and then it's straight away - from what they say).
Anything can be said. Ok. I understood. So, by default, need to be prepared for the worst: that information about you is stored and can be transferred to third parties.
If you use tor or use a public WiFi service then you'll be much more hidden.
As far as I know, it's not enough to use tor with default settings, but that's another topic for discussion.
In our country, to connect to public WiFi, need to specify a phone number. Well, you understand how hidden it can be and someone already wrote above that public WiFi is not the best idea.
If the Bitcoin mixer uses Cloudflare they have enough information about their user saved. However, they didn't save any of their customer data theres information the hacker that access their website will get.
Can you briefly say for overall development what information can be obtained using Cloudflare?
Never mixer huge BTC, always use Tor, and make sure you use 3 direct mixing methods (decentralized mixing should be included).
Can you talk a little more about this? Or in what topic it is possible to find out?
I have no idea how this service works.
It's hard to discuss privacy of mixers if you don't know how it works, or haven't at least tried it.
I touched not so much on the technical aspects of privacy, but more on information of a general nature.
Different mixers work in different ways.
Ok. Has this topic already been discussed on the forum, where I can fill the gap in my knowledge?
If at the beginning of the birth of crypto industry mixing services there was no, in view of the fact that the bitcoin network was considered anonymous, now everything is going to the fact that not a single transaction will be carried out without mixing services.
New times - new needs.
