Suggestions

Suggestion #1 - Improve the mixing process

For those wondering how Whirlwind works, it's quite simple. An example of flow of the process is as follows:
1. Your input is received by Whirlwind.
2. Your input is moved to the Whirlwind hot wallet.
3. You receive your output from the Whirlwind hot wallet minus your chosen fee and after your chosen time delay.

If you are using the "Fast" option with one input and the same output, no matter what fee you use you can be sure that anyone that is trying to track your blockchain transactions will be able to match the output with the input and the use of the service would be quite worthless. If you must use "Fast", you must break up the inputs into multiple outputs and use the time delay. If you really want to achieve privacy, I believe that the best way to go is to create multiple notes, combine them and create multiple outputs of different value at different times.

No matter which method you choose however, it is very easy to distinguish that your input was sent to Whirlwind and that the output has come from the Whirlwind hot wallet. This should be noted if you do not want future receivers to know that you are using/have used Whirlwind. The pitfalls of this come forward if Whirlwind is ever black-listed or tagged by chainanalysis or another related company, or if Whirlwind is ever sanctioned (like TornadoCash). If this happens, all coins would be tainted. Whether you believe in tainted coins or not, any service that you use that does believe in tainted coins would probably ask you questions due to the usage of Whirlwind.

It should be noted as well that it is possible to receive outputs including inputs from your deposit. Use a longer time delay if you want to avoid this. It should become less common as the service increases in usage.

I believe that the service should be improved with a more sophisticated mixing process. I suppose that in its infancy, it is fine for the time being. Though I can't see it being viable for too long if there are interests who do not want Whirlwind to be a solution for privacy in the future. These forces evidently exist after recent events in the last month.

I suppose that one positive about the mixing process is that one can easily verify the reserves on hand. I was able to confirm that whirlwind controls at least 4.98 BTC at the time of writing (not including cold storage, if any)

Thanks for your review - I have a few comments regarding the mixing process and I'll explain why it's far from being easy to track or insecure as you suggest, in fact it's quite the opposite. Please read this previous message of mine first:

¹ Chipmixer was the only centralized mixing service which I did not break fully. However, I did not put much work into checking this mixing service.

Contact him, and if he accepts to give a paid review, I think that this will contribute a lot to gaining trust in your mixer service (at least for some here)

I went through his report and altough I'm sure we already fixed the issues outlined by him, I will still try to get him to do a paid review for your confirmation.

Coinmixer.se (the service used as example in the report) works like most mixers on the market today, and they all have the same big issues in common:
1.Maximum delay time is limited
2.Maximum amount of output addresses is limited
3.No option to have higher outputs than inputs
4.Use of mixing codes

These issues make it possible for anyone to perform blockchain analysis with relative ease. The privacy set (number of deposits your output transaction could have originated from) which is the most important figure in my opinion, is reduced to only the transactions that were performed during the time limits imposed by the "maximum delay". And since you also know the maximum number of output transactions each deposit has, it's not that difficult to deanonymize it.

We solve all these issues by introducing the Note mechanism. Let's see how the above issues apply to Whirlwind:
1.Maximum delay time is unlimited
2.Maximum amount of output addresses is unlimited
3.Outputs can be higher than inputs (combine Notes)
4.We don't use mixing codes

Since the user has the option to deposit and withdraw whenever he likes and we don't impose a limit, blockchain analysis becomes useless. In the case of coinmixer.se it's written in the report that they had about ~1000 deposit transactions a week. If we assume we'll have the same, then the privacy set of Whirlwind will grow by 1000 every week.

After 10 weeks every output transaction could originate from any of the 10,000 deposits into Whirlwind, and this figure will only grow as time goes on. With other mixers it doesen't matter how many deposits they have in total, the privacy set doesen't increase.

The use of mixing codes by a service confirms that the privacy set is very weak and introduces other risks since it can link your transactions. If a mixer does what it's supposed to do, it shouldn't matter if you get 'your own coins' back because anyone that ever used the service could have withdrawn those coins.

Regarding the other points you made:
-It's impossible to connect your inputs and outputs with 100% certainty thanks to the way the system works. Even if you are using Fast mode with only one output, that output could have originated from any deposit since the start of the service. Obviously you know which ones your transactions are, but for an outside observer it's impossible to know for sure since Fast and Note outputs are identical and you can't know which option any user chose when he deposited.

-The fact that it's easy to notice an output comes from Whirlwind is by no means a disadvantage in my opinion, all other mixers have their clusters tagged by analytics firms. Hiding that you're using a mixer is not Whirlwind's goal, our goal is to break the link between your transactions and we do that better than any other service, including those that send you "clean coins from centralized exchanges"

At first glance that may sound "better" since you get coins with low AML risk, but you need to ask yourself what do you value more and why are you paying for a service of this type in the first place?

Getting low AML risk score coins, but them being easily traceable back to you? Or getting potentially higher AML risk scores with Whirlwind, but achieving real privacy?

I would choose the latter any day, and Whirlwind was built with that in mind. It's all about numbers

If low AML risk score is really that important for users then I could offer this option too, without compromising the privacy. It would add more costs and complexity to the whole operation and that's why I'm not very keen on doing it, besides the fact that I don't believe it does anything better for your privacy.

If low AML risk score is really that important for users then I could offer this option too, without compromising the privacy.

You can't do this, and I suggest you not attempt to, because AML score is purely subjective and is pretty much against Bitcoin as currency. Buying it means you approve it, which is where the trap lies to.

I completely agree with you, my concern is that even after some time users won't understand the huge advantages that Whirlwind offers from a privacy perspective since the service works differently than what they're used to. I hope it won't be the case, but if it happens then I'll be obliged to look for ways to offer what they want while not making compromises on privacy. It'd suck, sure, but it's a business at the end of the day so offering the best privacy means nothing if noone uses it.

[BenCodie]

Thank you for a very detailed response! I addressed what I could below

Regarding the other points you made:
-It's impossible to connect your inputs and outputs with 100% certainty thanks to the way the system works. Even if you are using Fast mode with only one output, that output could have originated from any deposit since the start of the service. Obviously you know which ones your transactions are, but for an outside observer it's impossible to know for sure since Fast and Note outputs are identical and you can't know which option any user chose when he deposited.

One thing I will address is about a singular fast input and output. Sure, the output may be from other coins. However, since the whirlwind hot wallet address is known, the same output and value would allow an outsider to easily deduce that the user deposited via Whirlwind, and received an older input. Hence, the level of privacy is lower/the chance of compromised privacy is higher. This is assuming a "not normal" threat level I suppose.

This is kind of irrelevant - Don't take it as a part of the discussion about the service itself, though I think it's worth noting. One could also argue that one sending Bitcoin between multiple wallets means that there is never 100% certainty that it is the same person, with each hop potentially becoming a new owner. However certainty is not always a primary factor, deduction of possibility is more so a primary factor. In this example, it would not be 100% certain that the hops are the same person, though it would be easy to deduce that it is.

-The fact that it's easy to notice an output comes from Whirlwind is by no means a disadvantage in my opinion, all other mixers have their clusters tagged by analytics firms.

It's not a disadvantage unless whirlwind is sanctioned like TornadoCash was. While right now it is tagged the same way as other apps, a sanction would mean that every coin involved in the service would be on high watch. Any usage where coins can be held from that point forward, would be a sure thing. Sanctions are possible if the app, its service and its coins can not be seized. If ChipMixer was operated as well as Whirlwind seems to be, I am quite sure that they would have been sanctioned rather than seized.

Until then, you are right that in this point in time, it's not really a huge disadvantage. It's more of a potential pitfall in the future if anything unfortunate like what I described were to happen for some reason.

At first glance that may sound "better" since you get coins with low AML risk, but you need to ask yourself what do you value more and why are you paying for a service of this type in the first place?

Getting low AML risk score coins, but them being easily traceable back to you? Or getting potentially higher AML risk scores with Whirlwind, but achieving real privacy?

I would choose the latter any day, and Whirlwind was built with that in mind. It's all about numbers

I fully understand and am in agreement with where you are coming from in regards to breaking the trace via the improved methods that you offer (Notes, combining notes, time delay etc) in comparison to receiving "clean coins from centralized exchanges".

If low AML risk score is really that important for users then I could offer this option too, without compromising the privacy. It would add more costs and complexity to the whole operation and that's why I'm not very keen on doing it, besides the fact that I don't believe it does anything better for your privacy.

One thing that I did in my review was directed it toward the audience (potential users). For me to feel comfortable posting the review, I should aware anyone who is not so savvy of the risk of using centralized services after using a mixer. The principle would usually apply to all mixers. If you were to make a development that would seek to reduce AML score risk as well, definitely work on it on a fork of the current version that way the current version is not disrupted. If you did take that route and it actually worked 100% of the time, it might not increase privacy any more than the existing service but it would definitely increase usability. In fact, I would say that it would be a breakthrough, as this would essentially beat analysis companies.  

If low AML risk score is really that important for users then I could offer this option too, without compromising the privacy.

You can't do this, and I suggest you not attempt to, because AML score is purely subjective and is pretty much against Bitcoin as currency. Buying it means you approve it, which is where the trap lies to.

If it worked 100% of the time, why not? Fighting it is different to buying into it. By creating a sure-fire development that beats AML scores, that is fighting. Not buying into it.

It should be noted too that a development like this would probably create a lot more pressure or liability for operation...how much more than what there already is, I don't know!


The "AML score"/"tainted coins" discussion could go on debated for some time. I'm happy to leave my opinions as they are and respect everyone else's as right or wrong as mine would be. I don't think any of us can speak in certainty on the subject nor the best approach toward it.

Happy to continue the conversation regarding the other points relating to the service with @whirlwindmoney though, to help improve their app or knowledge-base.

[BlackHatCoiner]

but if it happens then I'll be obliged to look for ways to offer what they want while not making compromises on privacy.

It's impossible for a fungibility-preserving service to comply with anti-fungibility. And you also can't offer such thing without compromising privacy; AML score is without doubt resulted from the ability to trace the coin's origins. If you want low risk, you need to provide low quality product.

whirlwind.money

1. Design

When using a software service, beautiful design is very important.  This is the first thing that the user of the mixer encounters, and the first impression cannot be corrected.  I liked the design of the whirlwind.money website.  It has a black and green color scheme that references the Matrix movie aesthetic.  I liked the corporate logo in the form of a green swirl.  The overall impression of the website design is technology, cyberpunk and speed.  Designers received money for their work not in vain.  The design of the site turned out to be very successful and futurological.

2 Technical support service

At the next stage, I decided to test the technical support of the project.  This is a very important service, as the user must be sure that he will be promptly helped if something goes wrong.  I quickly found the tech support email address on the site (whirlwindsupport@proton.me).  Technical support uses the Proton mail mail service to communicate with customers.  This e-mail service was developed by ex-CERN employees and the servers of this project are located in Switzerland.  The project uses the AES-256 encryption algorithm and is considered fairly anonymous and private.

I then decided to check out the Mixer support team and asked them an emotional question (pretending to be a not-so-smart and emotionally unstable customer).  When testing, I was interested in two things - how quickly I will receive a response from the technical support service and the constructiveness (adequacy) of the text of the letter.  The next day I received the expected response.  This is not indicative of poor customer support as I contacted tech support late last night.  At the same time, I want to note that in this situation it is possible to use a special mail bot that will explain to the client that if he wants to communicate with a person about his problem, he will be able to do this only tomorrow morning.  I liked the answer I got in the morning - the operator politely asked me to reformulate my question and made his guess about the possible cause of the problem.

3. Mixing

For mixing, I used an Android smartphone.  My smartphone has a large screen of 6.67 inches, it was quite comfortable to use the mixer on such a screen.  I didn't use TOR browser.  I used only Fast mode, besides it the mixer supports delayed mode.  In the first step, I indicated Bitcoin - the address to which I planned to receive funds.  I chose one address (in practice, you can specify two or more addresses).  Then I chose a delay time of 1 hour.  I then checked the address of the letter of guarantee (it was genuine) and downloaded it.  In the last step, I deposited satoshi (0.0011 BTC) to the bitcoin address offered to me.  The whole process went smoothly, I got my Satoshi.  At the same time, I was faced with the fact that the commission paid turned out to be more than I had planned, based on the information indicated on the site.  

In general, I got a very interesting and valuable experience.  Mixers, in my opinion, are a very important element of the crypto industry.

Post already reserved has been deleted.

This is my review of Mixing in Whirlwind as well as his experience.
I don't know why the Clearnet site can't be accessed even though I have activated JavaScript in a normal browser but it still can't be accessed, is it still under maintenance?
Well, I used the Tor Browser to continue mixing in Whirlwind.

Site design Whirlwind

In my opinion, the appearance of the site is not fancy, but it looks very simple, between the black color as the background, white color as the font, and the green color for the header. At first glance, this is very simple. I like this look.

Deposit
The deposit type chosen is FAST

Here I'm just mixing on one address to try the first time in a whirlwind but I'll try again with multiple addresses later and it's greater than the minimum.
In this process, at first the Captcha didn't appear properly, I even had to refresh it so that the Captcha code would appear again and this only happened at the beginning, while several times after that it ran normally and I could see the Captcha clearly.



After I successfully made a deposit to wait for confirmation I tried to click "refresh transaction" but what happened in almost 1 minute was in a black blank state and had to wait a few moments for it to appear normal, but I think this needs to be improved so that it is faster where we should not wait any longer.

I don't know if 1 minute is almost long or not which is clear to me it's enough and maybe the whirlwind party can refresh even faster than usual.

Even multiple clicks of "refresh transaction" remain the same.



After waiting for almost 30 minutes, finally I can see the status of the deposit has been received and it depends on don't confirm it so it can be seen there.

After doing everything I had to wait over an hour to receive the bitcoins back in my wallet.



After the deposit status was confirmed I waited and just let it go but after more than an hour of receiving bitcoins the display here has not changed where the mixing has been successful, just waiting on what is in the picture.



Those are some of the little problems that I experienced, I know I want to make a whirlwind review so they can improve better and faster but with this experience it will definitely help a little whirlwind with its little problems.

After all the steps were completed, I was still curious why the Clearnet site still couldn't be accessed in a normal browser, but when I opened it with the Clearnet version of the TOR browser, I could access it.

One more thing, I sent a few questions via e-mail but the replies took quite a long time, more than two hours, still no reply, I don't know whether the queue is long enough or not, and that's how I feel.

Review Campaign
/🍀/

Tor V3 and/or Clearnet.

<sup>Disclaimer:First things, the use of this service to make my transactions anonymous does not exempt me from
my responsibilities as a citizen.

Hence! I believe in the right to privacy and consequently the anonymity of a transaction it is a part of that,
my privacy.</sup>

/🍀/

Goals; This Review is made in two Chapter.

Chapter 1: fast deposit. I want to evaluate how fast it is and if it is true that in five minutes I could have my request ready.

Chapter 2: basically know how it differs from Fast.

In both cases we will analyze the process, we will highlight its virtues and deficiencies, determine if it is more accessible to what type of users, e.g. ,friendly for not so advanced users and we will end with my general vision of how satisfactory my user experience was to review.

My Review

Intro.
First impression before going to what is to be done here, a "mix" or better to say whirlwind.
We find ourselves with a minimalist interface, which seeks to deliver exactly what you need at first hand, a simple Page Home and just what you come to do, it is not a place for the frequency of daily visits or in-depth reading.

But!, perhaps for the web version, you can have it, then, a better impact friendly and it is a little day and night button.
Come on, as I said, just what is necessary at first impression, but in my case I don't like the black background, I would change it, at least in the desktop version.

In general, the visitors to this type of service are advanced users, so surely the niche determines that less is more, and yes, it is true, but the simple process of information that is needed from both parties (user-whirlwind. money) can be improved, alerts, etc. in fact they exist, but I repeat for an average user they can be better.

I mention this situations where applicable, hence MINIMALIST doesn't mean less friendly.

These types of things can help improve user traffic and make these sites more accessible to all and consequently a real and measured use to the "common" privacy needs/services.

In fact, it is what encourages me to carry out this Review, as long as one can verify the origin of their funds vs. the legal requirements of each country, the users do not have to fear using these services, so, again, it is about improving their anonymity, not about evade responsibilities.

In fact, if you have doubts about the use of this service due to legal or any other type of situation, do not use it, you should feel comfortable and very calm when using this service.

Start the review process with TOR, but review access with Firefox, Brave, Chrome, no problem.

Chapter 1

The page loads quickly, then, I immediately like to find the why we are here, on whirlwind.money. So, I have two processes, Fast and Note.



To find out what these services offer us, click(!):

: gives us the information,



In this case we will select fast:

Then in step 2 you can enter up to a maximum of 10 addresses, you can distribute BTC in each of the addresses you add to your liking, keep in mind that the page has a default fee of 10,000 satoshi/addresses.

I like in this step the precise information they add regarding the advantages of using multiple addresses and time between input/output  transactions:



These fees may be in the average for (big-money) important transactions but almost $30 for 10 transactions with low 3-figure amounts, it  is very high fee, I used a single address in my case and ended up paying almost $3, this not including the network fee in the deposit.

I repeat, you have to remember the anonymity "service" to make this more massive, surely with the large transactions they receive, small transactions may seem insignificant but the more deposits there are, the environment benefits more. So at least the fast option should have a lower fee and a maximum deposit limit. Why not?

Now,  Choose service fee, it is defaulted to 1.5%.
But, please! whirlwind.money  you could leave it default at the value of 0.25%.



Why? well, on two occasions I had to go back to change it.
Anyway, I like that it can be accessed manually or by moving the bar.

Complete Captcha

Click on the GO button.

so... and from here I start counting the 5 minutes...(!?)

Deposit:

Keep in mind the information on the screen is very clear and precise.

Download guarantee letter

DO NOT share this current page/link with anyone since your anonymity can be lost.
This page will be deleted 24 hours after the deposit confirms

use the button

Make the deposit use the Qr option (recommended) or simply copy the address.

and after that we have the final step:



After a few minutes the transaction appeared on the screen, BUT despite the fact that 4 confirmations marked in my wallet, the status of 1 confirmation was still maintained on the page, it really exceeded 5 minutes and did not reach 2 confirmations.

end of Chapter 1...

Cons
-  Doesn’t have no log policy

Did you really mean it [a] cons 🤣
It's a mixer, not banking database LOL

@Hhampuz, just to let you know, I am still working on my review. Mixing are in progress. After 48 hours received the fast option coins. And now progressing note options. I think so far I have spent over 3 to 4 hours in total. Other day around 2 hours and today since the last 2 to 3 hours I am on their website and their competitors' websites. Understanding what the F is going on behind these mixers. I will do some of my usual things after writing the post.

Let's not tell much until I have my review ready but for Whirlwind, it's a long road ahead. I guess my review will be brutal but I will try to keep the brutality as minimal as I can LOL.

Here is my review!

Whirlwind.money is a reliable and efficient bitcoin mixing service that helps users increase their anonymity and privacy while using the cryptocurrency. The platform has several features that set it apart from other bitcoin mixers available in the market.

One of the most notable features of Whirlwind.money is its user-friendly interface. The website is designed to be intuitive and easy to navigate, making it simple for users to mix their bitcoins with just a few clicks. This feature makes Whirlwind.money a great option for beginners who may be new to bitcoin mixing and want to ensure that their transactions remain anonymous.

Another important aspect of Whirlwind.money is its fast mixing times. The platform is designed to process transactions quickly, allowing users to mix their bitcoins and receive their new bitcoins in a matter of minutes. This makes it ideal for users who need to make quick transactions and want to ensure that their transactions are completed in a timely manner.

Additionally, Whirlwind.money allows users to choose their preferred mixing level for added security. This feature enables users to select the level of privacy they need, depending on the sensitivity of their transactions. This ensures that users have complete control over their transactions and can choose the level of anonymity they need to protect their privacy.

So, how does Whirlwind.money work? The platform uses a multi-sig that accepts bitcoin deposits from one address and enables withdrawals from a different address. This multi-sig acts as a pool that blends all deposited bitcoins. Once funds are withdrawn by a completely new address from these pools, the on-chain link between the source and destination is severed, thus anonymising the withdrawn bitcoin.

It is worth noting that the strength of the platform is directly linked to its number of users and the size of the pool. The more users deposit into the pool, the stronger it becomes. This means that users can help to improve the overall security of the platform by using it and encouraging others to do the same.

Whirlwind.money offers two options for users: "Fast" and "Note." The "Fast" option is the most convenient way to use Whirlwind, as the entire process takes less than five minutes and doesn't require further visits to the website. On the other hand, the "Note" option acts as proof that the user is owed bitcoin by Whirlwind and can be used to withdraw at a later time. Notes don't have expiration dates or management fees, they can be combined, and there is no limit on the number of withdrawals from a single note. This option achieves superior privacy since it provides the user with full flexibility regarding the mixing process, rendering blockchain analysis useless.

Whirlwind.money recommends using Notes, as they provide far greater privacy and security for the platform. By not only enhancing privacy for the user but also imposing a delay limit to withdraw bitcoin and making it possible to not only withdraw one deposit to multiple addresses but aggregate multiple deposits into one withdraw address, it means that any withdrawal could have originated from any deposit since the beginning of Whirlwind.

If users encounter any issues or problems with their transactions, they can contact Whirlwind.money's support team at whirlwindsupport@proton.me. The website also provides a comprehensive list of common issues and solutions to help users troubleshoot any problems they may encounter.

It's not just that this review is basically useless, but this guy has most likely used AI to generate this text:

My Review whirlwind.money
When I am using this on andriod with Clearnet link on the Opera browser with VPN, I noticed that after off the VPN, the browser appeared blank and unresponsive "Backend offline" issue Please try again later but I reloaded the page I was pleased to see that this issue resolved itself after restarting the browser.


Fast and Note on Whirlwind
 The Curiosity led me to explore the two methods available on the website - Fast and Note. Upon testing both methods, I discovered that the only difference between them lies in the first step. In the Note method, we do not need to provide a BTC address, but it is crucial to keep and write down the Private Note as it functions similarly to a private key. Losing or damaging the Private Note would result in the loss of deposited funds, hence the need to handle it with care.





In the second step, there is no difference between the Fast and Note methods. The critical divergence lies in the final step, where the Fast method allows users to wait for their mixed BTC to arrive in their wallet without having to revisit the website. On the other hand, the Note method requires users to withdraw their mixed BTC.



Fast Method
While using the Fast method, I encountered a minor issue with the address box being too small to view in its entirety. I suggest that the developers extend the size of the box to facilitate double-checking and ensure that the mixed address is accurate.



Some suggestions:
Use a "Refreshing, please wait" message instead of a screen refresh.
Allow users to enter exact amounts for multiple addresses instead of using percentage sliders.
Provide the option to split notes as well as combine them.
Determine if two confirmations are necessary for small deposits.
Increase the size of the address field on the withdrawal page for easier verification.
Consider lowering the minimum deposit to allow for consolidation of multiple small deposits.



Conclusion
I found the Whirlwind Money and its mixing methods to be easy to use and effective in maintaining my privacy when conducting transactions. However, I urge other users to exercise caution when handling the Private Note and double-checking the mixed address to prevent any potential loss of funds.

As a participant in the whirlwind signature campaign I figured I should also try/use the service to get a better understanding on what I am promoting.
I will try to keep this short and informative, not trying to stretch this post to make it look more detailed or to earn more money

Background information about my mixer knowledge:
I have used another mixer a few times in the past so I am not what you would call a regular user but I have an understanding on how a mixer should work I guess.

Here are my thoughts:
I really like the name and design of whirlwind as it is creative and stands out from other mixers.

The clearweb site would not load for me sometimes. Right now as I am writing this, it is also not available.
-> I had to use the .onion link later this evening

I like the "quick deposit method" where you dont have to create a note and can just send bitcoin to one address and receive them on another address.
Privacy-wise it is probably not as good as the tradiotional way though.
For this review I have chosen the faster way.

The instructions are pretty simple and anyone interested in a mixing service should be able to follow through.

Having a minimum fee of .25% seems reasonable to keep whirlwind in business but I wonder if it would be financially possible to make the fees completely voluntarily. When mixing 100€ I wouldn't mind paying the 25 cents in fees so it's alright I guess.

For testing purposes I sent 50€ to be mixed and sent back to me after 10 hours.
It cost me .00184788 Bitcoin (including transaction fees on my side) and I received back .00171851 Bitcoin which amounts to a toal of roughly 7% fees in my case which consist mostly (~ 77%) of the fixed fee of .0001BTC per address.
Mixing larger amounts will therefore have less fees proportionally.

I would recommend saving the guarantee letter to have proof in case something goes wrong. It is also quite handy if you forgot what options you chose in the first place (which happened in my case) because you can look up what fee you chose for example.

Would I recommend whirlwind?
Yes I would, if you are looking for a mixer.

Will I use whirlwind personally?
If the service is available the next time I need a mixer I will definitely use whirlwind.

As much as already been reviewed and though I have not read them all, I have read some of the reviews in some parts therefore would not want to reiterate the functionality side of things as that has been covered extensively in the reviews here. I would like to review my overall experience and views after touching on the two types of options to mix on Whirlwind.

FAST
This was a simple process. I entered the withdrawal address and chose to receive the amount within zero hours. As expected, I received the funds in under 60 minutes.

NOTE
After the amount was sent I withdrew the Note and chose to receive the amount within zero hours, which they did.

OVERALL VIEWS
I used the service twice (once with Fast and once with Note options) with the minimum 0.001 BTC sent on both occasions. I also used the lowest 0.25% fee on both occasions.

This is an easy to navigate website, there is very little going on with regards to excessive hyperlinks and focus is mainly on the core aspect of the business (which is mixing). The letter of guarantee is made available to download. When sending funds, two confirmations are required before any mixing takes place.

The captcha is an essential part of stopping spam and bots flooding the website, I did not find this one a problem with the 5 characters but during one test of refreshing I am fairly sure I entered the characters correctly but it took four attempts before I finally was allowed to proceed. Not sure what happened there but most probably my error rather than software or configuration issues.

After I withdrew the funds, I tried to go back and try again to withdraw and already withdrawn amount (for testing purposes only and not with the intention of scamming) and the pop-up alerts with a notice can be seen in the images above.

One thing that I noticed was after the withdrawal takes place, it shows Balance After Withdraw 0.00000001 BTC which gives the impression that the end user is owed 0.00000001 BTC (when that amount will be taken for the transaction fee) and it caused a little confusion. A quick attempt trying to withdraw again will show the pop-up alert above.

For the sake of testing functionality for this review, I should have withdrawn to several addresses but opted for one. Also, for both transactions I used Tor browser and found no issues with the settings on the strictest level.

Maybe I will revisit this review and update it if/when I re-test the Whirlwind service with multiple address withdrawals and by using clearnet. My review took place some time back but I posted the images and review just now when I had ample time.

POSSIBLE FUNCTIONALITY TO CONSIDER
Possible improvements or nice-to-haves would include a system where a withdrawal Note can be used to withdraw a percentage of the full associated amount. Technically, it might not be too difficult to have a superseded letter of guarantee to accommodate the disparities between the deposited amount and withdrawn amounts but the Whirlwind owner will know if this is possible (or even feasible) or not.

It could also be useful for a user that has deposited funds at Whirlwind to enter the Note and then have an option to generate a second Note or several Notes for an amount from their balance which could then either be used to withdraw another time or to provide to someone else for example in the form of payment for goods or service or trade. If there is a demand for this sort of service it might be something for the Whirlwind owner to consider implementing one day.

Earlier, the website on Tor was accessible but the clearnet came back with this:

I was testing whirlwind mixer for several days and I finally finisihed today and managed to find some time to write this review.

I visited both clearnet and onion version of website, but clearnet was not working for me, that is fine since I has intention to test mixing with Tor browser, but clearnet version should be released asap.
Whirlwind onion version worked very good for me and I used both deposit types Fast and Note during my testing.
First thing I noticed is missing information what is minimal amount of Bitcoin that can be mixed, so I had to find that info in Bitcointalk forum (this should be added on main page and in FAQ).

I like the freedom website is offering to select fees (from 0.25% to 4%) and hours (from 0-200), but I would like to enter numbers manually typing, not only with slider that is not very precise.
Anyway, first I selected Fast deposit, my custom hours and fees, with my BTC address, and saved my guarantee letter.
Everything went fine and I received mixed coins as expected, this Fast mode is easy for everyone.

 

Next I tried was Note option for mixing, and I choose custom time and fees, than I downloaded provided Note after I sent my coins.
I decided to wait for day or two before withdrawing my coins to achieve better mixing results.

There was nothing complicated with Note option, just remember to download and save both guarantee letter and note code.
Missing this part could mean you could lose your coins!

 

Everything worked fine but I noticed few things that can be improved, and I received few errors during Note withdrawal.
I also tried entering note that I withdrew before and I received message that Note is invalid or balance is empty.
I don't know what cause COULDN'T PROCESS WITHDRAW error, but maybe withdrawal was still in progress and I clicked WITHDRAW button two times.
For Invalid note I am sure I tried to enter old note again to see what happens.
I didn't combine notes yet, but this is on my to do list.

 

I have no complains about mixing procedure, but there are some small issues that can be fixed and improved.
Maybe WITHDRAW button should turn gray when I clicked it, or it should be replace with withdrawn message, because I don't remember I saw any message about that.
Minimum (and maximum) accepted amount of Bitcoin 0.001 should be clearly seen on main page, like I said before.
Clearnet website should be released without cloudflare if possible, and it should suggest people to use onion version for mixing.

Whirlwind came out recently, just after the Chipmixer story. I'm sure the launch was planned for later, but the closure of CM made the launch of this mixer accelerated.

Your online presence is a must to build your trust, and without trust, nobody is interested to use your service
I believe the person is quite active in our community and I appreciate it. Having spoken with some of them, I know they are people with a lot of knowledge and I always think it's a shame they don't share it with us on the forum.
The person seems to accept criticism and debate. Criticism is better, it's what make you grow up, not congralutations.
Reading him, you can see that he really wants to make a place for himself in the mixers' world, by adding value and trying to be different from other mixers.

- Website:

I found that the server is hosted by Njalla, an anonymous hosting and domain name provider, known among people who are interested in anonymity. (Njalla was created by the founder of the Pirate Bay)
It offers an extra level of anonymity, which makes it impossible to easily trace the owner of a domain name since there is no information about the identity of the user.

So this blender starts the anonymization from the beginning

- Website security:

I did some testing on the site and found nothing special, except for 1 thing with the HTTP Strict-Transport-Security header but it's not so important and I reported it to the site. They solved the problem a few hours later. There are maybe 1 or 2 other things, but I think they are false positives and I would tell the admin directly.

- Website design:

Simple and effective UI and UX for the user, but personally I'm not a fan of dark designs because it hurts my eyes like dark mode. But basically, I don't have a good eyesight. As they say in my country "you can't even see a cow in the bathroom. Your eyes are like 480p videos on youtube".
The captcha is not always easy to read. But then again, the problem is me
Hard to argue about tastes and colours as you know.


- How Whirlwind works:

I'm not going to do tutorials with lots of pictures because I think it's useless. The site is so easy to use and understand that even my grandmother who is soon 100 years old can use it.
If you have any doubts, the FAQ will answer your questions

There are 2 ways to mix your bitcoins: The "Fast" option and the "Notes" options.
Notes being much more efficient for anonymity

Here is an overview when you want to mix with the "Fast" option: I used 3 receiver's BTC adresses with 3 random fees, but you can use only 1 adress if you want.



And here is an overview with the "Notes" option:



What's the difference between Fast and Notes? Again, the Faq says everything you need to know:




- Results:

I create fresh wallets, and mixed bitcoins using both the "Notes" and "Fast" options. I then analyzed the hash, transaction,address
Here, I used the same tool used by small and medium companies such as Gate.io, LocalBitcoins,... to comply with international regulations. It checks wallets and transactions for dirty money with databases such as Crystal

With the Fast option:




- The bad things:

To answer this, I would have to ask myself: if this were my site, what could I do to improve it? No idea, except to make the clearnet version more stable, but being in the beginning, it will certainly come with time. You can't achieve perfection on day 1.
He seems to be constantly working on the clearnet version, which may be consistent with what I said. The site was planned for later, but the Chipmixer story made the launch to go faster.

- Short conclusion:
It does the job perfectly and this mixer seems promising for the long term

Here is my review Whirlwind Money
I recently had my first experience with a Bitcoin mixer service, and I must say, it was a positive one. Initially, I was hesitant to use mixers because of the negative reputation some have for running away with coins. However, after learning that Whirlwind, a reputable manager, was overseeing the process and that the funds were being held in escrow, I decided to give it a try with a smart amount of Bitcoin.




The website's interface was clean, easy to navigate, and user-friendly. It had two types of deposits, fast and note, with note being a new feature for me. I decided to try both.


I started with the fast method, adjusting the delay time to one hour. I found it straightforward to add addresses and set the time for each address to receive the funds. However, I encountered a minor glitch where I couldn't delete all but the last address form. Also, when I refreshed the page, it became blank, but clearing the browser data helped.


I then tried the note feature, which was simple to use. I adjusted the service fee, generated the withdraw note, and copied it, being careful to store it securely. When I wanted to withdraw the funds, I had to subtract the withdrawal fee from the amount I wrote otherwise, the withdraw button wouldn't work.

I withdrew the note funds and waited for the delay time I had set. The fast transaction landed in my wallet, but the note transaction didn't arrive after two hours. Unfortunately, I couldn't access the clearnet domain anymore even on multiple browsers.


I then accessed the website using Tor and discovered that my withdrawal didn't work because I had used the same wallet address to receive my funds as the one I had used to send them. The website advises using a unique wallet address, so I tried again with a new one, and it worked.



Overall, I was impressed with Whirlwind's support for bech32 addresses, low fees, and Tor V3 support. The only concern I have is the "address valid for 24 hours after generation" feature, which could be problematic during network congestion. However, having the note should be enough to guarantee access to the funds.

This is my first mixer experience with Whirlwind was a good one, and I would recommend it to anyone interested in using a Bitcoin mixer service

Did you really mean it [a] cons 🤣
It's a mixer, not banking database LOL

@Hhampuz, just to let you know, I am still working on my review. Mixing are in progress. After 48 hours received the fast option coins. And now progressing note options. I think so far I have spent over 3 to 4 hours in total. Other day around 2 hours and today since the last 2 to 3 hours I am on their website and their competitors' websites. Understanding what the F is going on behind these mixers. I will do some of my usual things after writing the post.

Let's not tell much until I have my review ready but for Whirlwind, it's a long road ahead. I guess my review will be brutal but I will try to keep the brutality as minimal as I can LOL.
