https://www.atobmixer.com AtoBMixer offering monero mixer, why use mixer for monero ? taught monero was untraceable
they also offer mixing for 16 different altcoin
but mixing monero is not worth it or am i missing something here ?
Monero is nearly perfect but there is a intentional attack called EAE attack that makes the receiver vulnerable if the sender intentionally wanted to find about sending many transactions and have a look at the volumes.
Monerooutreach.org explains it as
"Moneros ring signatures provide plausible deniability, but they arent perfect. We model examples where two colluding parties E attempt to learn information about an individual A. By sending outputs to individuals and tracing their transaction graphs, these colluding parties may perform powerful statistical tests to learn significant information, especially for repeated transactions where they would not normally occur by chance."
Monero mixers claims to stop this.
But the only party who can argue about the possibility of the senders are the exchange sites. I don't even think EAE will be working with the individual.
The exchange site is the only party who can ask the identities of the users.
EAE is still a possibility to argue some candidates who are having the possibility to be called as spenders.
Add more mixing to the monero will actually solve this problem.
