It’s just that the decoy selection algorithm picks decoys in a specific way. Its patterns can be exploited, but don’t stress about it. Churning will make up for it, it’s not that big of a deal. Just avoid spending outputs exactly after 10 blocks as it’s waaaaay more common for real spends than decoys (we can see that the Monero blockchain has way more spends on <20 blocks old outputs than the decoy algorithm proposes), especially when churning. Wait at least a few hours to a few days between churns

I didn’t really understand anything x)

Either are fine, as long as you have churned enough. Typically, the more time between transactions, the better it is. Withdrawing once per month will probably be absolutely fine.

The recurring usage patterns of XMR are either spend outputs quickly, or wait a long time. Spending old outputs will stand out a lot, but spending newly created outputs (like 15 blocks old) will also stand out quite a bit.

More time also means more chance of your outputs being included in transactions of other people, so more decoys at the time of spend.

I’m not exactly sure of what you meant.

I’ll try to answer the best I can, can you reformulate pls?

And yea sorry it’s pretty much always me that goes on the statistical things and traceability because that really interests me, but as you can see most people will tell you that it’s not really needed, and realistically, for 99% of people, no efforts will be made to monitor their transactions. It’s still nice to know that and churn if you’re extra paranoid like me, or you have a threat model that justifies you go this route.

XMR is a lot less traceable that regular crypto, and no one will follow a random person’s transactions for no reason. But on the other hand, churned XMR is a lot less traceable than XMR used directly. It’s all about how far you need to go and you’re willing to go.

Do note that churning might harm the amount of decoys overall, as you’re creating 2 outputs, 1 of which is a 0XMR output that you’ll never use, so you’ll never generate a transaction with it, and as such, won’t blend it with 15 other transactions. It’s not significant, but if everyone churns, that might lower the average amount of transactions your output appears in. We’re still very far from that happening though. And no, statistically, generating a 0XMR output will not help other people find the real output with value (or know that you churned) because it’ll only on average reduce by 1 the amount of transactions your output will appear in. The current average should be close to 16, so that’s not reliable enough to track you.

And again I spoke too much and talked about another subject that you didn’t ask for x)

Depends on your threat model. If you’re not being monitored, then repeatedly churning might be too overkill

You’ll never be able to properly block it

You can just go to Reddit instead. Same thing.

Damn I never understood it but now it makes sense thanks to you

Yea it’s ugly 😭

The sweet smell of cancer

Bro used <> instead of !=

You’ll have to explain me how 15 decoys are enough to make you untraceable, there is still roughly a 1 in 16 chance that a transaction your output is the real spend in a transaction where it is included.

Imagine you are A, and B and C are two different third parties

If B -> A -> C, then all good

But if B -> A -> B, then there is a 1 in 16 chance (in the best scenario for you) that in B’s eyes, you were the real spend. Add to that the fact that most people don’t churn and B doesn’t have many customers, and it becomes a lot more likely that you were the real spend (I’d bet my money on it).

CEX or not, you’re still traceable

Seems good!

About the Monero software, try using Feather Wallet. It gives you more infos about your outputs (you can select each one individually), handles everything better, and usually syncs faster (with remote nodes). I advise using Tor nodes (Tor support built-in) or using a VPN

Use a trusted remote node, as they’re currently pretty much able to track which outputs are used as decoys, as your client asks for them

Locally syncing by downloading the blockchain is still the best way as you will leak less things, but is super slow. Pick your poison (or run your own remote node!)

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!

Best $15 spent :)

Best answer

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
