What is the minimum amount of Bitcoin that can be mixed?

Per Trade, the minimum amount you can send in total is 0.001 BTC.

Per Output Address, the minimum amount you can send is 0.0001 BTC.

What is the maximum amount of Bitcoin that can be mixed?

In the footer of this site, we display the current trade limits, see Figure 1.

Hot Trade Maximum is the maximum you can send where the Mixer has the ability to send Outputs instantly after 1 Confirmation. Coins held in these Wallets are entirely automated and are connected to the internet at all times.

Cold Trade Limit is the maximum that the Mixer can successfully mix, outgoing transactions are signed off by a human operating a hardware wallet, "not constructed", but signed off after viewing the whole trade.

What is your fee?

It varies between 1% and 2%

How many Output Addresses can the Mixer send to, in 1 go?

The Mixer is able to send to, up to 20 Output Addresses in a single Trade, either in 1 transaction or spread over multiple transactions of different denominations, over a scheduled time of your choosing.

How many Mixer Deposit Addresses can I use?

The Mixer generates a unique set of 10 Bitcoin Deposit Addresses for each Trade.

You can either send the full required amount in one go to a single deposit address, or you could spread the total amount over multiple transactions of different denominations, over a longer time period of your choosing.

Do you have any mixing suggestions / tips'n'tricks?

We are going to create an article about Bitcoin mixing, including suggestions on how to best use Anonymixer, our initial suggestion is performing N-to-M based trades, where the number of Output Transactions is different to the number of Deposit Transactions, i.e. 2 Output Transactions to 1 Deposit Transaction, or 1 to 2, or 2 to 4, etc.

How do I know you won't run off with all my money?

We provide Digitally Signed Letters of Guarantee that are very easy to verify and can be done so independently.

If we fail to fulfil our obligations in one single trade that we guaranteed - and this becomes publicly known, that would be the end of our reputation and the end of this mixer. We can not fail once.

If something isn't working as expected or a mix hasn't completed successfully please email us and we will rectify whatever issue you have.

We're on Altcoins Talks, please come talk to us.

Do you keep any Logs?

We have a 100% No-Logs Policy.

The only thing that is kept on file is your "Trade" for the duration of it's life (72 hours).

The trade file is encrypted on disk with AES-256 bit encryption. Where the disk itself is separately encrypted with full disk encryption and that disk is in a machine which is physically separate from the machine which is serving this website to you and can only be communicated to through Tor via a secure Channel with Tor Client Authentication.

Once that Trade reaches the end of it's life, it is automatically deleted and no knowledge of it's existence will ever be known again, to anyone, including us.

Can I get my old coins back in subsequent mixes?

Yes. But we try very hard to ensure that this doesn't happen and continue to develop the code further to ensure this doesn't happen.

Aside from the fact that we have many individual coins/UTXOs, two approaches we currently take are;

1. Conf-Guard

Any coin that comes into the Mixer, must have at least 18 confirmations and be suitably thawed prior to leaving the mixer in any subsequent trade.

This caters for a user that makes multiple mixes in quick succession. If a user sends a coin to the mixer, there is absolutely no way that coin is coming back out of the mixer for at least 3 hours.

2. Most recent coins go out last

We have many Wallets. The Wallet which received coins into it last has the least likelihood and priority of being used to send out coins in subsequent mixes.

This caters for a user performing another trade on the same day or the next.

Does the mixer support multiple deposits to the same deposit address?

Yes, absolutely. Although this is discouraged. Please send your coins to individual unique deposit addresses.

We also fully support "Replace-By-Fee" Incoming Transactions and recognise when you've sent an updated Transaction with a higher fee.

Does the mixer work without JavaScript?

Yes. But with a limited set of features. You will have a better experience with JavaScript enabled.

We don't use a CDN to serve any files and never will.

We serve one JS file, anonymixer.js, which is obfuscated and can not be altered in any way or be ran on an imposter domain or onion address, otherwise it will simply refuse to run.

We serve it out with a SHA-384 hash, following the Subresource Integrity spec. If one byte of the JavaScript file is altered, the browser will refuse to run it.

If you're on what seems to be an Anonymixer website and the JavaScript doesn't work - then you know for sure that it's a fake website.

No raw source code of Anonymixer lives on the host / machine that serves this website to you. Every last drop is compiled, obfuscated and scrambled. Both server side code and JavaScript code.

Why don't you support huge mixes?, other mixers boast of being able to mix 200 BTC

We can't speak for other people's situations or finances. But personally, if we had a spare 200 BTC lying around, we probably wouldn't have spent time building a mixer in the first place.

Further, we wouldn't stick that 200 BTC in hot-wallets that are permanently connected to the internet, ready to send Bitcoin at the drop of a hat.

One can advertise to "mix" by simply taking BTC into a wallet, then transferring it out, minus fee, which would not fool even the simplest analysis software.

If the Mixer does other stuff behind the scenes, for instance sending your money to a Bitcoin Exchange to get alternative Coins back out, or converting to and from another crypto-currency. That's all cool, whilst the exchange doesn't freeze their account mid-mix, asking for "proof of funds" or the external service they rely on isn't exit scamming or has stopped working for whatever reason.

What do I do if I change my mind, or realize I can't fulfil the trade?

Anonymixer is designed to work well without human interaction, to handle the volume of trades that it gets. Dealing with an aborted trade and issuing refunds requires human interaction and effort.

Be very careful about spending all your Bitcoin. If you miscalculate with regards to your own Transaction Fees you can end up in a position of being unable to fulfil the trade.

If you are not able to 100% fulfill a trade, we can send coins back to the either your originating address of the deposit OR your output address of the trade, minus transaction fees and an admin fee.

Please send us an email, attaching the Letter Of Guarantee file and stating which deposit addresses you sent funds to and we will send funds back to you.

The trade must entirely time out before we can send any funds back. This is to protect you as well as us.

If you give us reason to believe you are performing illegal activity, we will be unable to assist you.

Do you support Native-Segwit / Bech32 Addresses?

Yes.

Do you plan on integrating with the Lightning Network?

Yes. Providing Submarine Swap Mixes, enabling users with the ability to both Pay Lightning Invoices as well as Deposit to the Mixer from the Lightning Network.

We would like to offer Lightning Network users the ability to partially settle/on-chain some funds from their open Channels onto the Mainnet, i.e. paying a Bitcoin Address without having to close their Channel.

As well as the reverse, i.e. Paying a Lightning Invoice without opening a channel and doing so purely from a regular on-chain Bitcoin Transaction, including for instance depositing to a P2PKH Mixer Deposit Address which results in Lightning Invoices getting paid behind the scenes.

What Wallet Implementation do you use?

We have written our own Wallet implementation, from scratch which has intense focus on coin selection, handling of change for maximum privacy, for both you and us.

It is very important to us that Blockchain Surveillance companies are not even able to identify (through cluster analysis) any of our Wallets or Transactions and that all of our Transactions look like regular transactions on the Bitcoin network by regular users doing what they do.

I have a great idea or suggestion, can we talk?

Yes, absolutely.

Questions like Could you support a particular BIP?, Will you integrate with JoinMarket behind the scenes?, if you're not doing so already?, Could you build an API to do X? etc. These are exactly the kinds of discussions we'd like to have.
