Interview with the owner of the service BitMaximum. Bitcoin mixer of new generation!
 
Hello!
In autumn, we began to cooperate with a Bitcoin mixer of new generation — BitMaximum. We wrote a detailed review about the service and the system of work, who has not seen - can be found here. Within a few months, users have accumulated a lot of questions to the owner of the service. Questions about the service came to us and to the owners of the mixer. We have decided to make a short interview with the Creator of BitMaximum service. It was interesting. Enjoy reading! 😉

OPENSSOURCE:
Hi. Tell us how and why you have decided to create a Bitcoin mixer?
BitMaximum Team:
Hello! Projects that existed at the time of the decision did not meet our requirements as the users of the services. They, by the way, and now do not satisfy. For example, to make the API work without the need to register and through Tor.

OPENSSOURCE:
Why is your product better than the other similar services?
BitMaximum Team:
We focus on user’s security. Our service does not require Java Script, does not require registration, we do not use Cookies, we offer an API that can be used completely anonymously.

The same applies to the payments — transactions are sent to the network only through the third-party services through Tor. Each time a random size of the commission of network is used. A random size of the commission of our system is used. Random delays between the outgoing transactions within one order are used.

We provide the maximum protection for our system. Our service works in paranoid mode. Our servers are inaccessible. But even if you just argue and admit the slightest possibility in the theory, in any case, the internal architecture of the project is arranged in such a way that even in the case of compromise of the server where the public part of the system is located, it will be impossible to replace the addresses given to the client. Of course, if the client does not forget to check the address signature before the payment. It is also worth to  note that the public XPub keys and private address keys are also not stored anywhere in the public part of the system.

OPENSSOURCE:
That's interesting. Many people worry before they make transactions through the mixers. Why it is necessary do not worry, but on the contrary, it is necessary to use mixers?
BitMaximum Team:
First, it is necessary to find a reliable partner and work with him. Secondly, we would recommend to avoid the system where Google captcha is used or distribution of private keys from the pre-prepared addresses. This is certainly convenient, but only if you are not confused by the complete lack of security.

Many people have an opinion that it is impossible to connect an address in the blockchain with its user. This is a big misconception. There are companies that analyze blockchain and data obtained from the public sources and connect them together.

Confuse these guys you can only by following these rules:
- always use Tor;
- work with disconnected Java Script;
- NEVER use the same address again, the rest of transactions is also ALWAYS sent to a new address;
- do not aggregate funds from different addresses after they have been passed through the mixer. If you are not satisfied with the random distribution of outgoing payments, you need to use manual settings;
- always use random fees when making payments;
- distribute the logically related transactions over time if it is possible;
- do not publish your addresses in the public places, including private forums, because someone else can allow them to leak;
- do not use the services that require the regular payment to the same Bitcoin address;
- do not share the private keys with other people;
- do not use online wallet services;
- using the HD-wallets to create own ways of derivation;

OPENSSOURCE:
You're talking about new technologies. What new technologies do you use?
BitMaximum Team:
As mentioned above, the main priority is the safety of users. Therefore, the main accent was placed on the creation of a multi-component system with a strict division of responsibility, where each component is isolated from the other. But details, for obvious reasons, we can't sound. In General, quite a lot of efforts are required to create a presentable design without the use of modern Java Script.

OPENSSOURCE:
Does It happen that the transaction is lost. What to do in this case and how to get your money back?
BitMaximum Team:
It is necessary to clearly understand what is "lost"! As have mentioned above, if the signature of the address is verified, that the system does when creating an order, the customer can be sure that the address belongs to our system. And then you need to carefully read the terms of service and  follow them.
 
For example, do not send more than one transaction to the given address or send less than 0.01 BTC. We ignore such transactions and do not send them back. Sometimes glitch the outgoing transactions. For example, before the recent BCH hard fork, miners transferred a lot of capacity to new networks and transactions in the BTC network took several hours. In all cases, please contact us at support, we try to answer as quickly as possible. In any case, we always process all transactions that comply with the rules of the service.

OPENSSOURCE:
Do you have difficulties in the market? Pressure from competitors? Unfair competition?
BitMaximum Team:
Competitors are constantly trying to put pressure. The main vector of attack is the mass creation of orders. If you noticed, we didn't have a captcha until the last moment. We had to introduce it precisely because of the pressure of competitors. But do not worry, we generate captcha ourselves, third-party services and Java Script are not used for this. We believe that the competitive advantage can only be the level of services provided. We prefer not to start sofa wars and pour mud on someone, but simply try to constantly improve our service.

OPENSSOURCE:
What is the benefit to the owner of such a service to keep and promote the service? Nothing is ever done for nothing. What's wrong?
BitMaximum Team:
There is no trick. We charge a commission for the services provided. Moreover, the more the customer agrees to pay, the greater level of security we can provide for him.

OPENSSOURCE:
What are your plans for the further development? What interesting things do you plan to make the service better?
BitMaximum Team:
The plans are quite extensive:
- expand the list of exchanged cryptocurrencies. Soon we will add BCH, LTC, ETH, DASH;
- open for all more expensive rates that will allow you to buy coins directly from the miners. Now this feature is in closed beta mode, please contact support if you are interested in this service;
— add the exchange of cryptocurrency, including instant;

OPENSSOURCE:
Thank you for your time. It was interesting. We wish success and prosperity to the service!
BitMaximum Team:
Likewise!
We hope that this information was useful for you and you got answers to some questions.
Thank you for your attention!

WHO ARE WE?

February 4, 2004: Facebook was launched. Youtube started on February 14, 2005 to become part of Google in 2006. In June 2013, Edward Snowden shared documents with The Guardian and The Washington Post about extensive surveillance of citizens of various states being performed by the US intelligence agencies including PRISM, X-Keyscore and Tempora project data. Meanwhile, Visa and Mastercard started blocking payments for services by several VPN providers. In 2015, the facial recognition algorithm developed by NTechLab won The Megaface Benchmark while the number of surveillance cameras on New York streets exceeded 100,000, according to PwC. In 2016, the European Central bank develops plans to withdraw €500 banknotes; two years earlier, Italy, France and Spain set severe limits on cash payments.

2017... The age of privacy is over. Keep this mind.
Any action you do, any transaction you perform online is being recorded. Your email provider is looking through your emails, mobile applications are sending stats to their developer, the government and multinational corporations are watching each step of yours. They know all about you.
We are a community of passionate IT enthusiasts to whom privacy is not a mere word. We realize that not all people are willing to sacrifice their privacy for the sake of a dubious advantage. That is why we developed a service that will let you safeguard yourself from too close an attention of third parties to your transactions in the cryptocurrencies networks.

Privacy is something you can sell, but you can't buy it back.

Can you explain how to use your API? Where and when do i need it?

You could use it to automate your mixing proccess, create your own mixer using Bitmaximum as your backend, implement them in your website or service, etc...

On the 'order created' page, i see the address to send my BTC to, then I see a signature and letter of gaurantee.

What do i do with the signature on the order page? You don't really say what to compare this to.

If i look at the letter of gaurantee, the sig in that letter DOESNT match the signature in the order created page. Is this what I should be comparing it to?

[BitMaximum]

WHY?

The most valuable asset Bitcoin showed to the world is the Blockchain technology. The Blockchain technology substantially increases the speed, privacy and security of money transfers. Bitcoins can be transferred from one person to another without any intermediary party involved, eg, a bank; the identity of each participant is safely hidden behind the long chain of the wallet address characters. That is its major competitive advantage over conventional payment tools.

However, few users realize that the address alone does not ensure absolute anonymity in the network.
To start with, many cryptocurrency exchanges require identification to be able to link the wallet address to a user. This happens chiefly due to the fact that Bitcoin has earned a reputation of a tool heavily used for illegal activities, therefore, there’s always a big chance that you can get ‘dirty’ coins in your wallet.

Considering the fact that the Blockchain technology by itself provides the fundamental ability to trace all transactions, in most cases deanonymizing a user isn’t that complicated. You always run the risk of getting in the crosshairs of intelligence agencies or cyber criminals which we regard as direct violation of rights and freedoms of an individual.

That is why we developed a service of Bitcoins exchange that uses conventional mixing techniques thus ensuring privacy and enabling you to be sure of the origin of the bitcoins you get.

We give you assurance.

We duplicate the answer from email:

You do not need to verify the signatures. This is just additional information. The service works in automatic mode, the money arrives in your wallet with a delay.

https://bitmaximum.io/en/faq/privacy
"To prevent any dispute, we are using the system of signatures.  Any new generated wallet address is signed using our Bitcoin wallet unique address. The transaction is easy to verify in the blockchain. This keeps you safe from getting into a situation when you transferred the coins, but never got them back.

How does it work? With the deposit wallet, you get a signature generated by the private key of your address, the public key for which is the address of our unique wallet. You can verify this signature using our wallet address, which eliminates the risk of having the address changed by an attacker to deposit funds."

[Dorvei]

At a time when all personal information is easily hacked the anonymity is  particular important.

I don't understand what you mean by this. You don't make it clear what I should be verifying. I see all these unique signatures your creating but you don't tell me how to verify them.

What do we need for?  Various examples from the life:

- Imagine that you are engaged in charity! It is generally accepted that charity should be anonymous. The philanthropist may have different reasons to keep the anonymity: the desire not to disclose his financial state, the unwillingness of appearance of a personalized sense of gratitude, etc.

- Imagine that you are planning to buy an expensive painting or antique item in your collection, but your foes, business competitors or journalists are just waiting to write about you in the newspapers, tarnish your  personality with a description of wastefulness, prosperity and wealth. 

- Imagine that you want to order yourself or a loved one an intimate gift that does not fit into the existing norms of morality of society. Therefore, Your person must remain anonymous.

- Imagine that you have a big business. We note the fact that most people and large companies have a desire (and often - the need) to keep the anonymity of their finances. And the reason for this is not that they are making something bad, but that they do not want to become the victims of other people's malicious or criminal plans.

There are a lot of cases of use of mixer. There are a lot of hackers who wants to steal your money and mixers is a good way for protection of money.

TryNinja, Thanks so much for helping me answer. Our topic is open on more than 200 forums, and for some reason the notification did not come to the mail that someone asked a question in this topic. Therefore, we support customers only through secure support mail. And you prompted all right instead of us! ) Thanks again.


PS.
We remind you that the tariff "only from exchanges" is becoming more and more popular. Very often, we change bitcoins through guarantors in personal escort through jabber. At the moment it is possible to exchange up to 3000 btc every day. Of course, by prior request. This also applies to altcoins. In exchange, you receive a pure digital currency with an active trading history from our trusted exchanges.

200 forums it is good for the promotion of the service. It is necessary that people will understand how is important to be anonymous. Very often anonimity becomes the part of safety.

What does your service do?

The major disadvantage associated with Bitcoin is that any transaction can be traced through the blockchain. Our service combines coins of different participants thus confusing the trails of transactions. The downside associated with using a regular service is that when paying out 'dirty money' you can get coins with a ‘dark’ history from other participants. We added the cleanup feature into the service so now you get funds from the Bitcoin exchange.

It is not only disadvantage of Bitcoin, it is desadvantage of many cryptocurrencies. Everybody can see how many money is on your wallet and check all your transactions. It is not comfortable when everybody knows about all your money transactions.

The authorities of the states wants to controll more and more cryptocurrency. The anonimity is necessary.

It is good that there are a lot of tariffs and every person can change the necessary tariff with the necessary level of anonimity and safety.

Why there is no manual selection of commissions and time delays?

Anonymity and convenience are mutually exclusive concepts. We've done some deep research. Yes and not only we, in literature and in networks
there are a lot of studies on the blockchain. Any information of this kind about the commissions, accurate time of transfer, etc. is a direct path to the absence of anonymity. We are not endanger our client. We made a special random % commission not to be 'burned" by to the exact %.
The tariffs specify the maximum percentage, they can not be above. We hope that other services of mixers will take this to the note and will use our rich experience and stop to give to users the information that simplifies the work of research companies and destroy all anonymity. We eliminate any possibility of deanonymity!
We can only provide you with such information. This is a random percentage of the Commission "from" and " to " for each tariff.

1) rate: { from: 0.005, to: 0.012 },
2) rate: { from: 0.01, to: 0.015 },
3) rate: { from: 0.02, to: 0.03 },
4) rate: { from: 0.045, to: 0.06 }

I agree that anonimity is on the 1st place and it is good that comissions change and it is not the same price.

[Dorvei]

My suggestion is to make a special blog and explain to people why mixer is necessary. Many people do not understand this.
