[banned mixer] Mixer Review Program #2
Bitcointalk username: iwantmyhomepaidwithbtc2Browsers used :-Mix 1 :Chromium Version 118.0.5993.70 (Official Build)
-Mix 2 : Tor 13.0
-Overall experience : I checked all the pages of the site with the two browsers mentioned above
+ Firefox 115.3.1esr (64 bits) on Debian and under Android with Firefox Focus 119.0
MIX 1 With Chromium (and Firefox) I couldn't access the captcha and couldn't use the mixer. I deleted my cookies, refreshed the page, took into consideration your
reply to mikeywith and stayed on the page while it loaded, but still the same problem. I tried with "private"/"incognito" window, same issue again. Not sure what was the problem, I never had this kind of issue with a captcha before. I encountered this problem yesterday too, when I tried to test your service, and it seems to be persistent on my end.
I had no problems with Tor browser, everything seems to work well:
So, let's go with Tor browser! I wanted to do the test with Chromium and Firefox, but it's not working at the moment. So I'm going to do the test with Tor, and try later when the problem is solved.

Delay:
As you can see above, the delay were respected.
For the third transaction, fees were very overpaid : 42,9 sat/vB instead of 13 sat/vB on average in block 813711

MIX 2 For this one I used the Tumbler code provided in my previous session.

Above, you can see the whole history for the test 2. As you can see, the transaction arrived on time (+10 minutes, so exactly the average block confirmation's time needed), and everything was flawless. I'm not a blockchain analyst, but looking with Crystal explorer I couldn't find my own address.
I sent 0.00148455 BTC and received 0.00125649 ; which is fine.
Transaction fees were a little overpaid 40 sat/vB instead of approximately 20 sat/vB

I'm now going to share with you my overall experience of using the product, as well as my various comments and questions.
About the mixing process :Despite the problems of using your services outside the Tor browser, I found the steps of mixing
extremely user-friendly, everything clear and well organized. It's one of the most pleasant mixers I've ever used. Your site updated itself almost instantly when my items entered the mempool, it's very responsive.
I like the Anonymizing meter, it's very user friendly:
It's good that users must tick the conditions + the reminder to download the letter of guarantee before everything else. Well done.
During the step 4 this informations appears and it is well managed, I find it very easy to read :
Once the mixing process is complete, I appreciated the suggestion to "Delete immediately" the order, which is good.
Before testing the mixing process, I began by exploring every aspect of the site, as I usually do when I come across a mixer I don't know.
I really like the design of your site, it's clear and modern.
Your website is responsive, I had no slowness of any kind, no matter what web-browser I used. The fact that you've integrated a dark mode is great. It's one of the most user-friendly mixer websites I've ever tried on Android, kudos for the mobile version!
However, my first impression was mitigated : I told myself that if I had to discover Tumbler randomly -outside the context of this review-, I'd wonder if the service was still active, and if a team was still really in charge of it.
Despite the beauty of the site, I had a sort of "ghost town" feeling when I was browsing on the site... Let me explain why :
The support can't be contacted :
Same issue with Chromium and Firefox :
An error has occurred. Please refresh the page and try again.
I've tried two days in a row and the problem persists, and I've also refreshed the page several times and the same problem persists.
Your Twitter account is empty, no avatar, no post.
I'm not sure it's right for you to leave this X account linked to your site, it gives an impression of being left behind. You could share on X your blog articles for example. I guess it's not
-of course- the number one priority, but any sign of activity is a plus when it comes to building trust.
Apparently, you have no active online presence outside your website and your Bitcointalk account.
Okay, it's not a big deal if you take these elements one by one, but as a whole, they give an impression of incompleteness.
In a sector where trust and reputation are essential, all these elements could lead new users to refuse to take risks, and to go and see some other platform. For example, showing signs of activity outside of your blog (which has irregular activity too) on Twitter, Discord or Telegram could be a real plus for federating a community of users and to reassure them. If I'd needed to contact the support, I'd have had to go to the FAQ, dig around and find your e-mail address. It would be nice to update the dedicated page. The fact that you are reactive on Bitcointalk is a big plus, but in my opinion, to reach more users, you need something extra. I know that multiplying accounts on social medias means multiplying risks (impersonation etc..), but
it should be possible to find a good balance between online activity/presence and risks.
Other comments and suggestions :
FAQYour FAQ seems to be quite complete and precise, the information is clear, and I can't think of anything in particular to suggest to change about it.
Terms and Conditions :Also, I've spent some time exploring your "Terms and Privacy" page.
I have some questions about the "Coin Filtering" part:
"The Service" may carry out verification and control of illegal activities with the help of a third party under a contract. "The Service" may terminate Your access to "The Service" with immediate effect for any reason - including, but not limited to, illegal or prohibited activities, at its sole discretion, and is not obligated to reveal the details of its decision.
You accept that "The Service's" decision to take certain actions, including termination for any reason at its sole discretion, may be based on confidentiality criteria that are necessary for "The Service's" security protocols and risk management. You accept "The Service" is not obligated to reveal to you the particularities of its security and risk management processes.
Are we supposed to understand that you could collaborate with blockchain analysis companies if it was requested? Or some my data could be shared to a third-party company? In any case, at first glance it seems rather vague. If you could reassure us about this point, that would be welcome.
Fees BTCI use mixers regularly, of course I look how much cost the fees, but to be honest, I'm willing to pay the price of privacy; I've paid up to 4-5% in the past, which is why I find your fees reasonable (even if from a personal point of view I'm not a big fan of a fixed amount of BTC + x% and I like to have a percentage only, but that's personal). It's not cheap, but it's not expensive either, when compared with some of others mixing platforms. All good.
I'd like to make it clear that for this test, I wasn't looking to save on fees or anticipate them at all, I wanted to test the service with small amounts so this is necessarily disproportionate. A regular user would of course take more care not to send such a small amount with 3 output addresses. Translations :I can only check the French language, but I'd like to point out that the site's translation is more than a little unreliable.
It looks like it's been translated with GPT or an automatic translation tool. Most of the mistakes are in the FAQ, but the whole site has issues with the translation. For example some terms are translated in a literal way when it doesn't apply at all in the context of crypto mixing ("pièce" for Bitcoin, "code a tambour" for Tumbler code, for example, but there are
many more).
If other languages have been translated in the same way, I'd advise you to recheck everything when you can.
Conclusion
You seem to be very responsive to the feedback you receive, so I'm not worried about the small accessibility problems I've encountered, I imagine they'll be quickly rectified.
Otherwise, I think the site could be more complete, especially from the point of view of branding your service. Nevertheless, it's been a pleasure to navigate, and use your site and service. I found it intuitive, fast, and the service was done as stipulated in the letter of guarantee.
I would like to thank you for giving me the opportunity to test your service, and to give you my comments and suggestions. I remain at your disposal if you want to discuss anything about this review.
