Review of [banned mixer]
I audited the website's UI and UX first and found some mistakes and some suggestions to make, but I will write it at the last of the review. Now first, I will share my experience with BTC mixer [banned mixer] and what problems I faced (if any). I first compared the [banned mixer] with other mixers and found some resemblance in UI features but most of the features Tumbler had while many other mixers don't.
First Mixing
Security Level: Basic
Browser: Google Chrome
Service fee: 0.4%
Delay: 4 Minutes
Amount sent: 0.0015
BTCI will receive: 0.001294
BTCAs aforementioned I sent 0.0015 BTC to [banned mixer] and due to the network congestion, my transaction got delayed for like 1 hour and 49 minutes. I set the delay time to only 4 minutes, and security level to basic, and only one receiving address (I prefer one only). I just had to wait due to the congestion which would have been solved if I had used an RBF-supported wallet. But I used Trust Wallet (TW).
Well talking about
first mixing, the experience was great, I really liked the captcha feature because it will reduce the bot attacks that money launderers might use to make quick TXs and it will also prevent the overloading attacks. I did not find this (captcha) feature in any other mixer (I would mention names here of the ones I have checked but I prefer not to, I hope that might not be a problem).
The UI was so smooth and lag-free, even though it uses JavaScript. I really liked the calculator feature but of course that's not something new, some popular mixers already have a "fee calculator". I did find some missing things that will make the UI more user-friendly. For example the following one:
Consider them as suggestions:1. Write somewhere in the red area that, you can add up to 10 different receiving addresses. The only way was to click the Plus icon to check how many receiving addresses we could add while if a small line is written there, then it will become easier.
2. You guys should add the total receiving amount too when we increase the number of receiving addresses. You can add that section right there where I marked red. It will come more handy while keeping track of how much we are paying on fee and how much we are going to receive in total. I had to use a calculator. I know none of the other Mixers I have experienced, have this feature besides just a simple fee calculator, but it will be super comfy and UI will become more user-friendly.
3. It would be great if we would manually write the percentage to allocate to each address (when we add more then one receiving addresses). But most of the mixer don't have this feature too, I think its on purpose. And just to add, I really liked the strategy of not allowing users to divide the amount into equal parts like in 50% 50% parts. No matter how much I tried but we can't divide them in equal parts. First I thought that's due to the slider but later I came to remember that they have already wrote on their website that
Divide the amount into unequal parts.
Now, I thought I should check the level of privacy it has, I tested it on 3 different platforms:
1. AML telegram bot (@cryptoAML_bot ) --> where the risk was around
27% (which shows that, the address was linked to another address (which was also mine) otherwise, according to that bot this percentage means the risk is not that much.
2. btctester--> where it shows the privacy level is
40.71%. Which according to this platform is average.
3. Blockchair too --> There the transaction was tagged as
critical due to the link to the address (source) which is connected to CEXs.
The results were different on each platform, and of course each have different matrices to track a TX. But so far, I manually checked the transaction history, and the results were satisfied, because besides an expert analysist no one would track the transaction (receiving wallet address).
Now I will try my 2nd Mixing and will compare the privacy scores of both, and also try to check manually.
2nd Mixing
Security Level: Standard
Browser: Mozilla Firefox
Service fee: 1.8%
Delay: 6 Minutes
Amount sent: 0.001294
BTCI will receive: 0.000.00107071
BTCAs stated above, I used Mozilla Firefox (browser) for the second mixing on [banned mixer] and the experience was smooth as it was on Google Chrome. I faced no errors and problems at all. The big errors were already spotted by the early reviewers and the team was so active that, they immediately covered most of the errors. Well, We will talk about team at the end.
Well, for the second mixing, I still used Trust wallet. I set the delay time to only 6 minutes and selected the security plan of "Standard". Receiving address was still the one. Because increasing addresses will definitely improve the privacy score, but I wanted to compare the Basic and Standard at same settings of receiving addresses. So, I kept it same (means only one). I also used the tumbler code but of course it don't have any discount yet, but eager to use the discounts in future.
I faced no problem but the suggestions are same, that I wrote after first mixing. Besides that, the mixer works smoothly without any lags or problem. Really surprised to see the smoothness it is like some old and experienced mixer.
Checking Privacy Score1. Checked the privacy score on the AML telegram bot (@cryptoAML_bot ) --> the score was
58.6% which according to that bot's setting is not good, It consider as highly risky but in reality it should not be in highly risky category. Well, Let's see others.
2. On
btctester it still shows the same score that it showed in the first mixing -->
40.71% 3. On
Blockchair the results was better, now it shows a moderate privacy score of
60In conclusion to the Privacy score, Standard security level did played an important role and the score of privacy can obviously increased by adding more receiving addresses or delay time. Means Standard is better than Basic and that is proved by blockchair result.
Team and Support
Contacted the support to ask questions about their project because I did not faced any technical issue. The team replied me saying that they will answer within 12 hours. After receiving a reply I can tell how fast they were. Till then, I wanted to say few words about the team, as they really showing their enthusiasm in this project, because they instantly worked on all the suggestions and errors, that early reviewers reports, like the following ones.
- Addition of Dark Mode
- Addition of Delete chat option
- Addition of delete logs before 24 hours manually
- Language issue of going to English after refreshing page.
- Addition of Bech32 address.
Ok, I received the reply after 25 minutes, Which is very long time (but once you got there attention then you will get reply in minutes), I think if they will decrease the delay in response, then there will be more trust of users on them. And they should have an alternative contact system other than website only. There Twitter profile is also outdated, they should update it and also remain active there for online awareness (if they want it).
Problems I faced- Any thing I wrote in the box, after sometime, it disappear automatically while it should not.
- Whenever I write something and want to send it I have to click on the send button, while it should also be done by clicking enter key on the keyboard, it also did not work with shift+Enter. Which means, we have to click via mouse on the send option.
User Interface:
The UI of [banned mixer] is so friendly, and easy to understand, that even a newbie with no crypto knowledge would understand what is happening here and how to mix BTC. The overall, UI experience was good and smooth. But I think some of the following things need corrections:
1. On the homepage, this multimedia (video) was not working, I tried to click it on different browser too, but it did not played any picture or video, I think you guys should make it work.
2. We all know that, Twitter has rebranded to "X" even though the domain is not changed yet, but the Logo is changed in all over the world. So, you should also use the up-to-date logo of Twitter (opps), of "X" in the bottom. Acceptance of new changes increase impression.
3. A link can be given for users to direct go to the page you are referring to, Because it will be hard for newbies to search about Tumbler on BTT. More ease for the users will show more devotion and users will feel comfy with you.
4. I think you guys are trying to say -->
Send the BTC to the address while you wrote "Send the
transfer to the address." It is really very confusing while reading the website content, please correct it.
5. Your website name is [banned mixer] <-- last io are in small letters, but in your website content, you wrote io as IO (in capital letters) which seems to be unprofessional and not really good too. I suggest you guys to use the io everywhere. It would also help to rank your main keyword.
Final Words
Overall, experience is great, I tested the Mixer on two different browsers and faced no error, the mixing was smooth like butter. There was more than enough content to teach a newbie, how to use mixer and how things works.
Transaction fee was also lower than many other mixers which is a plus point. But could be reduced.
The time of delay should be increased (more than 3 days). Besides this, I think the team has working so fast that, they did not integrate a suitable dark mode.
The dark mode, is not matching with the theme of website. But that can be corrected with time.
I really liked this mixer and will use it further. I hope my suggestion will be of worth. Thanks for giving me a chance to review [banned mixer] mixer. Keep growing.
