If you are looking for a Bitcoin tumbler which can mix large-scale transactions, CryptoMixer is an attractive option. The maximum mixing volume was around 500 BTC at the time of writing which is pretty big as compared to other services on the market. In addition, the site enables you to adjust the fees and delay periods for individual wallets which further improves anonymization. 

What is the main benefit of this mixer? 

As previously mentioned, CryptoMixer specializes in handling substantial amounts of Bitcoins. The platform emphasizes its ability to maintain substantial reserves that are readily available for transactions. Additionally, it highlights that users can verify the authenticity of these claims by referring to their official Bitcointalk thread.

How to use CryptoMixer?

The site is user-friendly, but it is still worthwhile to familiarize yourself with all of its features to avoid mistakes when mixing bitcoins. In this review, we will provide a detailed walkthrough to help you understand how to customize settings and enable features on the tumbler.

Step 1. Launch the mixing process

Go to the site’s main page and click the Start button. 

Let’s go over all the settings you can adjust at the service so that you know exactly what each of those means.

Step 2. Specify the mixing code

A mixing code is a code you receive from a Bitcoin tumbler after you have performed your first transaction there. Subsequently, you can use this coin in order to make sure that you don’t receive any of your own coins in return for the new Bitcoins you send to the site. 

Whenever you use a new mixer for the first time, you won’t have any mixing code yet. And so you should leave this field empty. 

If you want to learn more about the inner workings of Bitcoin mixers, here is the great Guide on Bitcoin Mixers. Here you’ll find the detailed explanations for all the major terms and functionalities in this niche. 

Step 3. Specify the first receiving address

In the next field, specify the receiving address you want to send your Bitcoins to. A receiving address shouldn’t be connected to your identity in any way. Otherwise, this will undermine the whole purpose of your mixing operation.

Input the receiving address in the field shown on the screenshot.

We’ll talk about setting up multiple wallets in a bit. 

Step 4. Set the fee level

Below you see the slider for you to toggle between the different fee values. It is accompanied by the fee level name. 

If you drag the slider to the right, the level will change from standard to silver and then to gold.

In order to understand the difference between these three levels, click on the small arrow in order to see the descriptions.

Thus, at the Silver level you get the ability to set the delays for up to 24 hours, two output wallets and no fast payout confirmation. We’ll look into the other two fee tiers below.

Step 5. Create the second receiving address

Now let’s go above and create the second output wallet. To do this, click the Add address button. 

Step 6. Set the delay periods 

Now that we have the two wallets in place, we can adjust the settings for them. Of course, you can use just one receiving address, but we generally recommend using no less than two of them.

Let’s set the delays for each of the two wallets. To do that, click the Set Delay button. 

After you’ve clicked on the button, the slider will appear where you’ll be able to set the values. 

It is crucial for you to establish significant time gaps between the mixing delays. When you create a delay, it signifies that there will be a specific duration between inputting the amount and generating the output transaction.

By doing so, the mixer can effectively receive and process a certain number of transactions for other users during this interval. This serves as an effective measure to safeguard your mixing transactions from blockchain analysis attacks and maintain anonymity on the blockchain.

CryptoMixer.io, which has been reviewed here, stands out from other tumblers due to its unique feature. The fee level you choose directly affects your ability to adjust specific settings. Therefore, if you desire to prolong the payout transaction delay, opting for a higher fee is necessary.

If you drag the slider to the utmost right position, you will be able to set the maximum possible delays at 96 hours.

Step 7. Set the distribution percentages

The next step would be to adjust the distribution percentages between the wallets.

By default, the system divides the output transactions into the two equal shares. This is a big problem because it gets very easy for the blockchain analyst to identify that those output transactions are probably associated with your input transaction. Blockchain analysis is all about the probabilities and potential connections between the transactions recorded on the blockchain. Of course, nobody will be able to claim with the 100% confidence that the transactions are associated, but, at the same time, the receiving addresses you use will be deemed as associated and tracked for years to come. 

That’s why, using uneven distribution percentages makes a lot of sense for obfuscation of your transactions. 

Step 8. Add the third-tenth wallets

If you want to use more than two output addresses, you can click the Add address button and set up the needed amount of the wallets.

While you do that, the fee slider will automatically bump up.

Thus, you will be upgraded to the Silver Level. 

And if you want to use 6-10 output addresses, you will get bumped up to the Gold Level.

Make sure that you scramble the fee level values a little in order to make them more random as compared to the round levels picked for each tier by the system. 

Step 9. Calculate the final output amount 

You can also use a Bitcoin mixer as a clearing layer when sending out payments to other persons. CryptoMixer makes it easy for you to clean payments with a nifty calculator. 

First, click on the Use Calculator button.

Second, specify the final amount you want to furnish to that person in Field 1 shown at the screenshot below. 

The system will calculate the Bitcoins amount you need to send in order to generate the respective output transaction. 

Step 10. Continue with the process

Now that we have adjusted all the settings for the Bitcoin mix, you should click the Continue button. 

Then you will need to confirm the important terms of use. Make sure to read through the notice and remember that you can send the incoming transactions to the mixer’s account only within 24 hours. Any subsequent payments will not be recognised by the administrators as valid and will be simply ignored.

Step 11. Download and save the Letter of Guarantee

The Letter of Guarantee is a document which is used to prove that you did actually send the coins to the mixer and that the wallet address you see at this site is actually owned by the mixer.

Save this document securely so that you can produce it to the support time whenever you face any problems with your transactions. The administrators will not be willing to help you  without this document. 

Step 12. Send the Bitcoins to the mixer

Now, you are ready to send the Bitcoins to CryptoMixer.

As shown on the screenshot below, you can either copy and paste the wallet address or scan the QR code.

If you decide to use the address itself, you should always copy and paste the same. Since if you try to retype it, this might result in errors. And the transactions in Bitcoin are irreversible and there’s no support team to ask help from whenever something goes wrong. 

Step 13. Add additional incoming addresses

You can also add a number of additional addresses. To do that click the “Add incoming address” located below the already provided address. 

This is a unique feature and we think that CryptoMixer reviewed here is the only Bitcoin tumbler who has it.

Step 14. Save the mixing code 

At the last stage of the process, you need to copy and save the mixing code. 

We have provided a detailed explanation on the mixing code at the start of this review.

What is the maximum amount of Bitcoins available for tumbling at the service? 

The actual maximum amount of Bitcoins you can tumble at any specific moment varies. You can see the information about it in the second window. At the time of writing, it was 490 Bitcoins.

It’s a pretty large amount and we are certain that CryptoMixer will be able to successfully process your transactions for the large amount. 

Should you mix Bitcoins at all?

While some folks believe that Bitcoins are completely anonymous and there’s no need for enhanced anonymity here, it’s not completely true. The Bitcoins are pseudonymous.

The wallet addresses are completely anonymized which means that they aren’t connected to the user’s identity in any way. But the second you decide to withdraw funds to your exchange-based wallet where you have officially registered with your identity, the overall path on the blockchain gets shared with anybody around the world – both with regards to past and future transactions.

Now, anybody can freely analyse your purchases, buying habits, sources of funds and basically the amount of money you have in the bank account. Naturally, this goes against your understandable desire to retain confidentiality for your financial operations. Mixing your Bitcoins gives you just that. Mixers usually charge around 1-5% depending on the number of output wallets you want to use.

CryptoMixer offers the full set of the features needed to mix your Bitcoins. So if you are just starting up with mixing Bitcoins, give it a try. In particular, if you need to clean a big stash of Bitcoins.

Conclusion 

CryptoMixer positions itself as a perfect choice for large-scale mixing operations. The site says that users can clean up to 500 BTC. The system enables you to specify up to 10 output wallets while you can also adjust the delays and distribution percentages for each of them. In addition, you can set up the randomized fee values for better obfuscation. There are three tiers of fee levels depending on how many output addresses you want to utilize. The CryptoMixer team has presented official proofs for their Bitcoin reserves which you can familiarise with in their official Bitcointalk thread.
