Take a look at the one on my signature space (MixTum).

Hi. Are you running your own node?

Hello everyone, I need help to clean some bitcoins. Does anyone know about some bitcoin mixer?

What do you mean to clean some bitcoins. There are no clean or dirty bitcoin. You need to break the trace that's the better term for it. Check around the forum, you will find many mixers are there. So far I can remember: Yo!Mix, Sinbad, Coinomize, MixTum. I am yet to check MixTum. Already used the rest of it but I personally prefer Sinbad.

When you are mixing it's better to use more than one mixer. Send coins to mixer one then send the mixed coins to another mixer before bring them back to the permanent wallet.

Mixers come and go, so if you use them once, don't get attached to it because one day it might disappear.

If you're OK with creating an extra wallet, you can transfer your bitcoins to Samourai Wallet, which has a whirlpool mixing feature based off of Coinjoin (a many-input, many-output featuring inputs from multiple users and outputs going to multiple users), and then you can transfer the bitcoins from Samourai wallet back to your own wallet.

Also keep in mind that exchanges don't play nice to mixers - Don't send mixed BTC to exchanges e.g. Binance or they might give you trouble over it.

You can do it directly with Bitcoin blockchain, Bitcoin Lightning Network or blockchains of privacy coins like Monero and use DEXs to convert it to bitcoin.

With Bitcoin Lightning Network, you will support its adoption as well.

Are you asking about bitcoin mixer? You are joking! Yes, here wherever you poke click (the user's signatures), you will definitely get to some bitcoin mixer.

To be honest, even I can't decide which bitcoin mixer (after closing chipmixer) I would be willing to use if needed. Which of the existing (and promoted on this forum) can be trusted (if bitcoin mixer can be trusted at all) and which one can be recommended by users (only real ones with real experience using BTC-mixers)?

What is more ironical about "clean" bitcoins, is that some exchanges consider bitcoins "tainted" after a recent mixing process.

You can just make a few hops (transactions) to other addresses you have, to make that mixing undetected by exchanges.

Remember, mixers don't make your coins clean. They make them pseudo anonymous

[Medusah]

You can use joinmarket or whirlpool without trusting mixers with your money.  Don't trust anonymous strangers with your bitcoin.  Not your keys, not your coins.

If I remember it correctly, somebody said their mixed coins were classified as tainted even though they already move them through some addresses. So some exchanges might trace back to more than just one past transaction to see if your coins are "bad" or not. Although if you use a mixer that doesn't really make it hard for exchanges to see that you use them is a bad idea to begin with.

Any exchange is more than capable of looking back a few transactions to see where the coins have come from. A far better option is to stop using centralized exchanges which attack the very essence of bitcoin by treating it as non-fungible, and will spy on you and censor you if they don't like what they find.

There are now plenty of decentralized exchanges, marketplaces, merchants, services, and so forth, out there which do not spy on you and do not promote the provable nonsense that some coins are "tainted". Use them instead, and stop worrying about whether some faceless third party thinks your coins are naughty.

I honestly like what you said. I have also been using the term dirty and clean bitcoin without reasoning much about it. Could it be the name the government and exchanges gave to victimise people.
After reading your post I understood that I may have bitcoin sent me from untrusted source, although the bitcoin was not used to commit crime but to ensure privacy I decide to mix the bitcoin. By this, that bitcoin in the address is called dirty or tainted as the case may be. I prefer using the term you used "Breaking the trace".

Most of the TOS that exchanges are using specifically bans the usage of such services. However, the problem arises when you consider Bitcoin should be fungible.

Exchange can absolutely do so, but if you can prove beyond reasonable doubt that you weren't aware or otherwise associated with them, then it is fine. They have to actively prove that you are the one that is using it and you can use plausible deniability to your advantage. Afterall, they cannot prove that you were the one using the service unless you were to send it directly to your exchange without any hops.

I didn't know about this wallet, sounds very interesting: can you tell me something in more detail about the effectiveness of its mixing technique? Is it possible to spread the outputs over time like mixing services do?

[Lucius]

Hi. Are you running your own node?

Do you think someone asking a question like the OP would even know what a node is?

~snip~

Doesn't the mixer in your signature and mine solve that problem considering what kind of mixing process it uses?

[banned mixer] does not shuffle available funds in one or multiple pots, but exchanges incoming bitcoins with coins purchased from investors -  cryptocurrency stock exchanges.

In addition, I probably made hundreds of transactions with mixed coins that went directly to various CEXs and never one of them was blocked or challenged in any way.

[o_e_l_e_o]

Afterall, they cannot prove that you were the one using the service unless you were to send it directly to your exchange without any hops.

Even that is not proof. "I sold an old laptop to my friend. He wanted to pay me in bitcoin, so I gave him my deposit address for my Coinbase/Binance/whatever account. He paid the coins directly from the mixer to my account."

The bottom line is that as soon as a transaction has happened, you cannot say the bitcoin haven't changed hands. As soon as a transaction has more than 1 input and 1 output, you cannot say which bitcoin ended up where - indeed, "which" bitcoin is a concept which doesn't actually exist. The very concept of taint is provably nonsense. It is a triumph of blockchain analysis companies that they have convinced governments to force centralized exchanges to pay them hefty fees to peddle this nonsense.

You can leave your coins in Whirlpool for as long as you like, and they will continue to get free remixes. You can spend individual outputs as and when you need to. If I had ten outputs of 0.01 BTC being coinjoined, for example, I can easily spend one of those right now and leave the other nine in Whirlpool to continue to be mixed.

Are the post mix outputs on different addresses?

Example is cycling a little over 0.5 BTC in the 0.01 pool to create 50 outputs of 0.01 BTC. Does this means that all the outputs are sent to 50 different addresses on your Samourai wallet?

Do not mind me, I have not used Samourai Whirlpool before and I just want to be certain about it. But I think that is what the outputs should be, to different addresses.

I think this is true for most situations.

If you want to trade a 20usd for an Amazon card, you can certainly use a p2p solution, or some merchant or whatever...

But for people who are heavily invested in bitcoin and want to trade high values, this is not feasible.

Would you dare trade  1 or 2 btc in a p2p? This is very risky, and an exit scam is a real possibility. Additionally, people who live in developing countries mostly don't have an USD/EUR account, which narrow a lot p2p possibilities.

On the other hand, trading 2, 3, or even 5 bitcoin is quite secure in the biggest centralized exchanges.

you can just do 4,5, 6 hops... It is quite cheap to make an on chain transaction with 1-2 sats bytes.

Are the post mix outputs on different addresses?

Yes. Each output is on its own address and addresses are never reused.

Example is cycling a little over 0.5 BTC in the 0.01 pool to create 50 outputs of 0.01 BTC. Does this means that all the outputs are sent to 50 different addresses on your Samourai wallet?

Yes, although if you wanted to cycle 0.5 BTC, then the 0.05 pool would probably be a better choice.

I already made that point above. A number of simple "hops", with one input and one or two outputs is absolutely trivial to trace, and achieves literally nothing against blockchain analysis companies. And transaction with 1-2 sats/vbyte in fees aren't even being relayed at the moment, let alone confirmed.
