The more outputs you have/use, to more traceable you get. The more churning you do, the less traceable you become

I would advise to mix your outputs at different moments rather than all at once in a final big transaction, as those kind of transactions really stand out. If you’ve made enough churning it shouldn’t be a concern anyways but 🤷

On the other hand, mixing outputs early will also make you more traceable (but will lower the cost of churning, as churning many times many individual outputs is expensive), so I’m not sure it’s the best option either

False and false

Using CEX and sending multiple transactions to the same person will make it really easy to trace you. You just need to have an opponent that is willing to do it and has what’s needed (your government for example)

You got it right! It’s exactly that.

I personally put everything on the same account and use coin control to spend only specific outputs but that’s just because I don’t like changing accounts

You’ll have to know that one you spend an output on the second account, it will pretty much result in a change output that isn’t as much churned (still no link to the original withdrawal, but could be statistically linked to the transaction you just made with it). In the end it’s all about what you think are the capacities of your opponent, their motivation to get you, and the risk for you if that happens. Most of the time and with the current situation, no one is good (nor interested) at statistically tracing XMR, but that might happen in the future.

So relatable

Funni

And I hope the same for you brother!

until she breaks up with you 👀

I would argue that splitting an input into 2 outputs that’ll both go in the same wallet and could be used together would severely harm your privacy and make tracing easier

By the way, you can churn to your own wallet, as it’s not possible to link the output to the wallet. You can use the wallet accounts feature to separate coins

Just make sure you don’t use 2 churned outputs together (too early) or you’ll link them, and don’t use a churn output with an unchurned output. Feather Wallet with coin control is a good choice.

If you’re going to use 2 of your churned outputs together, that could relink the outputs together and make it stand out, although I haven’t really thought about it. It might not be that bad if you’ve churned enough, because at some point it’s logical that outputs from 2 big pools intersect

Plus it justifies deposits in case I sell, they won’t be like « where does the crypto come from? »

But yea in an ideal world that shouldn’t be required and we shouldn’t be spied on

XMR currently takes 16 outputs per input, where 15 of them are decoys and 1 of them is the true one

Assuming you’re not using any traceable pattern like churning every 30mins (you should split your churns, avoid churning too frequently), then the formula is 1/(16^(churn amount)).

So after 1 churn, there is a 1 in 16 chance (6.25%) that this transaction is yours. After 2 churns, it’s a 1 in 16x16 = 1/256 = 0.39% chance that the final output of the route is yours. After 3 churns, 1 in 16x16x16 = 1/4096 = 0.0244%

The probability decreases exponentially.

Please note though, that even after 3 churns, it’s still possible to figure out a link with you. 4000 outputs way less than the total amount of outputs in the blockchain, and you can likely be traced depending on your threat model. As an example, let’s say you own a darknet market. If you deposit to an exchange, you’ll be one of the few with a link to the output that came out of the market to deposit. The closer you are to the output, the riskier it gets. That example alone might not put you in trouble, but you’ll be put on a list. Now imagine this happens again. A second list is formed, and you appear in both lists. It is already really unlikely that the same person appears twice. Third deposit, you appear again. Now you’re probably the only one with this pattern.

Solution? Either churn a lot so that a lot of outputs are in contact (through being chosen as decoys at some point), so you’re not the only one to regularly have outputs linked with the poisoned output. Depositing outputs with no link at the time of deposit would also be beneficial, but that’s not always possible. That’s considering you got the worse threat model, which is a gov sending you outputs and getting them back (through CEXs). Another good solution: withdraw to DEXs!

The best prices are on CEX
