Bitcoin transactions leave a public trail on the blockchain that anyone can follow. If you’re hoping to hide your transaction history, Bitcoin mixing services might be what you’re after—they scramble the connection between sender and receiver.
Coinomize.is is a Bitcoin mixing service that breaks the link between your original coins and the ones you receive, making it nearly impossible to trace transactions back to their source. The platform claims to have mixed over 2 million bitcoins since launching in 2019. It works by pooling user funds and redistributing different coins to output addresses.
Bitcoin mixers like Coinomize live in a legal gray area. Privacy advocates argue financial anonymity is a right, but these services can easily be misused for illegal activity. It’s smart to weigh the privacy perks against the legal risks before diving in.
Key Takeaways
- Coinomize mixes Bitcoin transactions to break the connection between sending and receiving addresses.
- The service charges fees between 1.5-5% plus mining fees, and lets you customize delay times.
- Bitcoin mixing carries legal risks—always check your local laws before using these services.
What Is Coinomize?
Coinomize.is is one of three official domain addresses for the Coinomize Bitcoin mixing service, alongside coinomize.biz and coinomize.co. It’s been around since 2019, offering Bitcoin tumbling with customizable fees and delay options for better privacy.
Overview of coinomize
Coinomize mixes user coins with others to hide the original source. You need to deposit at least 0.0015 BTC, and you can pick processing times from instant up to 72 hours.
There are a few ways to tweak your experience:
- Service fees: 1.5% to 5% plus blockchain fees
- Time delays: From a few minutes to 72 hours
- Privacy controls: Higher fees and longer delays mean more anonymity
Coinomize deletes all user data within 72 hours of completing transactions. If you want, you can delete your order info even sooner.
The process is pretty straightforward. Visit the site, set up your order with your preferences, send Bitcoin to the unique deposit address, and after mixing, you’ll get “clean” Bitcoin back at your withdrawal address.
History and Reputation
Coinomize has been running since 2019, with no major security incidents or exit scams reported. It holds a 4.9 out of 5 rating from over 1,100 user reviews on dark web forums and marketplaces.
The service has built trust through consistent uptime and clear policies. Unlike plenty of competitors that disappear within a year, Coinomize has stuck around.
Customer support is available 24/7 through a ticket system. Most users get responses within minutes, and all tickets are answered within a day.
There’s also an Android app and Tor access for those who want extra privacy. These features show the team is serious about user anonymity and accessibility.
Comparison to Coinomize.biz
Coinomize.is, Coinomize.co and Coinomize.biz are the same service, just on different domains. They offer the same features, fees, and security since it’s all the same backend.
The different domains only serve as backup in case one goes offline.
Coinomize also offers a Tor Onion Browser domain: coino2q64k4fg3lkjsnhjeydzwykw22a56u5nf2rdfzkjuy3jbwvypqd.onion
Please beware of phishing domains, there are many of them.
Key similarities include:
- 1.5% to 5% fee structure
- Minimum deposit of 0.0015 BTC
- 72-hour data deletion policy
- Same processing time options
You can access your orders from either domain using your order number. This cross-domain setup gives you a backup if one address is down.
Multiple domains are for redundancy, not separate services. If a domain is blocked in your country or goes offline, just use the other one.
Which domain you pick really just comes down to accessibility or personal preference. Both are trusted in the Bitcoin privacy community.
How Coinomize.is Works
Coinomize pools user bitcoins and redistributes them through different addresses, breaking transaction links. It’s a centralized mixer, using time delays and offering transaction guarantees for each operation.
Bitcoin Mixing Process
To start, send at least 0.0015 BTC to Coinomize. Only one blockchain confirmation is needed before mixing begins.
Your coins get pooled with others, creating a big pot that makes tracing harder. You can pick a mixing fee between 1.5% and 5%, plus a 0.0003 BTC miner fee. Higher fees give you more anonymity.
Time delays are customizable, from zero up to 72 hours, depending on what you want. After mixing, clean coins are sent to your chosen output addresses, with random delays between each send for extra privacy.
Supported Features and Functions
Every transaction comes with a Letter of Guarantee—basically proof the address belongs to their servers, which helps if you need support.
After your first mix, you’ll get a unique code. This stops you from accidentally getting your own coins back in future mixes.
Key Features:
- Mobile app for mixing on the go
- Tor browser support via onion addresses
- Multiple output addresses for better privacy
- Custom fee selection (1.5% to 5%)
- Flexible time delays, up to 72 hours
All transaction logs are deleted within 24-72 hours. You can also manually wipe your order if you want.
Support tickets are available for any questions or issues. Replies usually come within a few hours, always within a day.
Mixing Algorithm Explained
The blender uses centralized mixing, combining transactions from many users. This breaks the direct link between where your coins came from and where they end up.
The algorithm spreads bitcoins across various wallet addresses in the system. Since these wallets hold funds from lots of different users, tracking individual transactions is next to impossible.
Algorithm Steps:
- Collection – Gather bitcoins from lots of users
- Pooling – Mix all funds in shared wallets
- Distribution – Send mixed coins to user addresses
- Delay – Add random delays between sends
Masternodes process the mixing, handling the technical side of combining and redistributing coins.
For multiple output addresses, random send delays are added. The system waits several seconds between each send, making it even harder to link transactions.
Privacy and Security Measures
Coinomize.is uses several layers of protection to keep your privacy intact. Advanced mixing, strict no-logs policies, and Tor compatibility all work together to provide financial anonymity.
Anonymity and Bitcoin Privacy
Coinomize.is severs the link between the original and destination Bitcoin addresses. It combines multiple transactions into one big pool, then redistributes coins to fresh addresses.
You can set custom delays between deposit and withdrawal—anything from minutes to hours. This makes it tough for anyone to analyze transaction timing.
Large transactions are automatically split into smaller pieces. That way, blockchain analysts can’t track payments by size patterns.
Key anonymity features include:
- Random fees for each transaction
- Multiple output addresses
- Custom percentage splits for each output
- New address for every mix
No registration or email is needed. There’s no direct link between your identity and your Bitcoin activity here.
No-Logs Policy
Coinomize.is says it deletes all transaction records after mixing is done. They don’t store your IP, transaction amounts, or wallet addresses once the process finishes.
All data gets wiped from their servers within 24 hours of completion. This includes every bit of input, output, and mixing info.
No personal info is ever required—no email, phone, or ID. You just use the service and move on.
Data handling practices:
- No permanent storage of mixing transactions
- Automatic deletion of session data
- No user accounts
- No tracking of repeat customers
Once the deletion period passes, you can’t recover transaction details. It’s good for privacy, but make sure you save anything important yourself.
Use of Tor Network
Coinomize.is is fully compatible with Tor for extra privacy. You can access it via standard browsers or through its .onion address for added anonymity.
Using Tor, you hide your real IP from the service and your ISP. There’s a dedicated Tor hidden service address, so you never have to reveal your location.
Tor blocks network-level monitoring, so ISPs and government agencies can’t easily see you’re visiting Coinomize.
Tor integration benefits:
- Access through .onion addresses
- No IP address logging
- Protection against network traffic analysis
- Anonymous browsing of mixing services
They recommend Tor for maximum privacy. Using a regular browser can expose your location and browsing habits to your ISP or other prying eyes.
Using Coinomize.is: Step-by-Step Guide
The process has three main steps: set up your wallet addresses, create and fund your mixing order, and receive the cleaned coins at your output addresses.
Wallet Preparation and Address Management
Before you start, set up clean Bitcoin addresses. It’s best to use new addresses that aren’t linked to your old coins.
Ideally, use a different wallet entirely for mixed coins. You can create fresh addresses in wallets like Electrum or with a hardware wallet.
Multiple output addresses make tracking even harder. Splitting your mixed coins across two to five addresses is a good move.
Each output address needs at least 0.0015 BTC. So if you want to use two addresses, you’ll need at least 0.003 BTC.
Setting up your addresses ahead of time saves hassle later. Write them down or store them securely before you head to the mixer.
Initiating a Mixing Transaction
To start, users head over to coinomize.is and create a order. The system instantly shows the total fees—these run from 1.5% to 5%, plus a 0.0003 BTC miner fee.
The platform then generates a unique deposit bitcoin address for this transaction. It’s crucial to download the Letter of Guarantee before sending any coins, just in case.
Key mixing settings include:
- Fee percentage: 1.5-5% (higher fees mean more privacy)
- Time delay: Up to 72 hours max
- Output addresses: 1
- Coinomize code: For repeat users, so you don’t get your own old coins back
Users can set a custom delay for each output address. Random delays help make it harder to connect transactions.
The system only waits for one confirmation before starting the mixing. It’s always smart to double-check all details before sending your Bitcoin.
Receiving Clean Bitcoins
Clean bitcoins show up at the output addresses after the chosen delay. The whole mixing process usually wraps up within 24 hours at most.
You’ll get coins from the big mixing pool, not your original Bitcoin. This severs the link between your old and new transactions—pretty handy, right?
The platform wipes transaction records automatically within 24-72 hours. If you’re extra cautious, you can delete your mixing order manually for added peace of mind.
If you use multiple output addresses, each one gets its coins at different times. There are even random delays of a few seconds between each payout.
Afterward, check that you received the right amounts (minus the fees). The Letter of Guarantee is your proof if you ever need to contact support.
Fees, Limits, and Guarantees
Coinomize keeps things flexible, with fees ranging from 1.5% to 5% plus mining fees. The minimum is just 0.0015 BTC per output address, so even small amounts are welcome. Each transaction comes with a Letter of Guarantee for security and authenticity.
Service Fees and Miner Fee
You get to pick your mixing fee—anywhere from 1.5% to 5% of the total. Higher fees mean your coins end up with a cleaner slate and better privacy.
Basically, paying a bigger fee gets you bitcoins with less traceable backgrounds. If you’re serious about anonymity, it’s worth considering the higher end of the scale.
There’s a flat miner fee of 0.0003 BTC for every transaction. This covers blockchain confirmation costs and doesn’t change based on your chosen mixing percentage.
Fees depend on your selected mixing power and delay preferences. Going for max mixing power with a 72-hour delay runs at 5% of your transfer amount.
Minimum and Maximum Amounts
The minimum to mix is 0.0015 BTC per output address. This keeps the service accessible, even for folks with smaller balances.
You can spread your mixed coins across up to 5 different addresses. Each output address still needs to hit the 0.0015 BTC minimum.
The platform uses several nodes and cold wallets, each with different balances, for security. This setup helps keep both user funds and the platform itself safer.
Maximum amounts aren’t fixed—they depend on what’s available across the network’s wallets. The platform keeps balance levels different on purpose for operational security.
Letter of Guarantee
Every transaction gets a digitally signed Letter of Guarantee using the public key 1CrywjDEzzpEMxdWzCDgtmZ3Tr57XrnANV. This letter confirms that the Bitcoin address provided is legit.
It’s your proof if there’s ever a dispute or you need to verify something. Always download this document before sending any coins to the mixing address.
If you need support, you’ll have to provide the Letter of Guarantee. Without it, the team can’t really help resolve issues.
You can check the letter’s authenticity with most Bitcoin wallets or online tools. Just compare the signed message against Coinomize’s official signing address.
Coinomize.is and Blockchain Analysis Resistance
Coinomize.is uses centralized mixing pools and customizable time delays to break direct links between input and output addresses. These tricks make basic tracking tougher, though advanced blockchain analysis tools can still pose a challenge.
How Mixing Disrupts Blockchain Analysis
The platform blends your bitcoins with coins from other users in a shared pool. When you send bitcoin in, you get different coins out—never the same ones you put in.
This process breaks the straight line between your sending address and where the coins end up. Blockchain analysis outfits like Chainalysis usually follow coins by tracing them from one address to the next.
Mixing creates “clean bitcoins“—coins that don’t have an obvious link to their original source.
Pool size matters, too. Fewer users at once means less “noise,” so it’s easier for blockchain analysts to spot patterns.
Temporal Delays for Enhanced Security
You can set delays anywhere from instant up to 72 hours between sending and receiving mixed coins. This helps throw off timing-based tracking.
Blockchain analysts often look for timing patterns to connect transactions. If coins move instantly, it’s a dead giveaway for automated tools.
Longer delays add more transaction “noise” between your deposit and final withdrawal. That makes it trickier for anyone to draw clear timing links.
The delay system really shines when you combine it with other privacy steps. If you go for instant withdrawals, you lose out on this timing protection and become easier to follow.
Centralization, Alternatives, and Limitations
Centralized bitcoin mixers like Coinomize.is work differently from decentralized options, and each comes with its own privacy trade-offs. Knowing these differences helps you pick the right tool for your needs.
Centralized Mixers vs Decentralized Options
Centralized mixers mean you have to trust one provider. The company controls the whole process and temporarily holds your coins, so if they get hacked or shut down, that’s a risk.
Decentralized options, like CoinJoin, mix coins without you ever sending funds to a third party. Multiple users combine their transactions right on the blockchain.
Key differences include:
- Control: Centralized services handle all mixing
- Trust: You have to trust the provider with your funds
- Speed: Centralized mixers are usually faster
- Ease of use: Centralized platforms tend to be simpler
Centralized mixers also face bigger regulatory risks. Governments can go after specific companies, which makes these services less reliable in the long run.
Comparison with CoinJoin and Other Mixers
CoinJoin is the main decentralized alternative. Wasabi Wallet and Sparrow Wallet both offer CoinJoin mixing, but each has its own twist.
Fee comparison:
- Coinomize.is: 1.5% – 5% plus 0.0003 BTC miner fee
- Wasabi Wallet: 0.3% coordinator fee
- Other centralized mixers: 4% – 7% usually
CoinJoin mixes coins into standard sizes with multiple outputs, making tracking much harder than with single-output centralized mixers.
But CoinJoin isn’t as beginner-friendly. You’ll need to understand mixing rounds and coordination. The best bitcoin tumblers often trade ease for stronger privacy.
Centralized mixers are better if you want something quick and straightforward. They take care of the technical stuff—just send your coins and get your outputs.
Limitations and Risks
Centralized bitcoin mixers have some real downsides. Regulatory pressure is rising everywhere. In many places, bitcoin tumblers are now seen as money transmitters.
Major risks include:
- Service shutdown: Companies might close suddenly
- Data retention: Some may secretly keep transaction logs
- Exit scams: There’s always the risk of operators vanishing with funds
- Government seizure: Authorities can shut down centralized sites
Privacy also isn’t perfect. Most centralized mixers don’t randomize output amounts, making it easier for analysts to track by amount.
Another headache: exchanges often flag coins from known mixers. You could end up with a frozen account or blocked funds.
Mixers with only one output per transaction are easier to trace. Multiple smaller payments are harder to link, but not all services support that.
Legal risks depend on where you live. Some countries ban mixing outright. Always check your local laws before using any crypto mixer.
Best Practices for Maximizing Anonymity
Splitting mixed coins across several withdrawal addresses, adding time delays, and never reusing bitcoin addresses are key for privacy. Layering these with other privacy tricks gives you the best shot at avoiding unwanted tracking.
Using Multiple Addresses and Delays
It’s smart to send mixed bitcoins to several different output addresses, not just one. This makes it much tougher for anyone to link the coins back to you.
Most mixers let you set up 1-5 withdrawal addresses. Each should get different amounts at different times, which really muddles things for anyone trying to trace the funds.
Time delays matter too:
- Set delays from 1-24 hours for each output
- Use random times, not regular intervals
- Longer waits mean better privacy, but you’ll need patience
Mixing up output addresses and random delays makes transaction analysis a real headache, even for advanced tracking tools.
Avoiding Address Reuse
Reusing bitcoin addresses is one of the biggest privacy slip-ups. If you use the same address again and again, it creates obvious links between your transactions.
Every address should be single-use—both for sending and receiving through mixers. New address every time, that’s the rule.
Address management tips:
- Make fresh addresses for every mixing session
- Don’t send mixed coins back to old addresses
- Use HD wallets—they generate new addresses automatically
- Keep mixing addresses separate from your regular wallets
If you reuse addresses, it’s easy for observers to connect your transactions. Even perfectly mixed coins lose their privacy if you slip up here.
Combining Techniques for Privacy
Mixing alone isn’t enough. The best privacy comes from combining several techniques and sticking to good habits.
Some solid privacy combos:
- Use Tor to hide your IP during mixing
- Wait weeks or months before spending mixed coins
- Break big amounts into smaller mixing sessions
- Try privacy wallets like Wasabi or Samourai
Timing is just as important as the tech. Don’t spend mixed bitcoins right away—give it some time to throw off tracking attempts.
If you make these practices routine, you’ll keep your privacy stronger over time than just mixing now and then.
Frequently Asked Questions
Coinomize gets a lot of questions about privacy, costs, timing, security, transaction limits, and registration. Knowing these details helps you understand how the service actually works and how it keeps your Bitcoin transactions private.
How does Bitcoin mixing improve transaction anonymity?
Bitcoin mixing breaks the link between your original wallet and where your coins end up. Coinomize mixes your bitcoins with others in a shared pool, making it hard to trace them back to you.
Every transaction gets a fresh wallet address. This removes the obvious link you normally see on the blockchain. Without mixing, anyone can track wallet addresses and follow the money trail.
After your first mixing session, Coinomize gives you a unique code. This makes sure you never get your own coins back in future mixes.
What are the fees associated with using a Bitcoin tumbler service?
Coinomize lets you pick your own mixing fee, anywhere from 1.5% up to 5% of the transaction. Higher fees supposedly mean a bit more anonymity, if that’s what you’re after.
There’s also a 0.0003 BTC miner fee tossed in, just to cover the blockchain costs. You can tweak the fee for each transaction, and honestly, it’s not a bad idea to mix it up—keeps your pattern from getting too obvious.
Can users specify the delay for the mixed coins to enhance privacy?
You can set your own custom delay before you get your mixed bitcoins back. That delay helps scramble the timing, making it trickier to link your transactions.
If you’re sending to multiple output addresses, Coinomize throws in random delays of a few seconds between each one. It’s a little thing, but it adds another layer of confusion for anyone watching.
The whole mixing process can take up to 1 hour, depending on your delay settings and how fast the blockchain moves that day. You get to decide the delay for each transaction.
What measures are taken to ensure the security of transactions?
Coinomize wipes all transaction records within 24 to 72 hours after everything’s done. They say they don’t keep user IPs or wallet info, which is reassuring—at least on paper.
Every transaction comes with a Letter of Guarantee. It’s basically proof the Bitcoin address is legit and belongs to Coinomize, which can be handy if you ever need support.
You can check the Letter of Guarantee with your wallet software or online tools. They use the same signing address for all their verification messages.
Are there minimum or maximum transaction limits for mixing coins?
The minimum you can mix is 0.0015 BTC per output address. That keeps things running smoothly and helps maintain privacy.
Coinomize runs several nodes and cold wallets with various balances. This setup helps them handle different transaction sizes and keeps user funds a bit safer.
Is it possible to access the service without registration or providing personal information?
Coinomize actually lets you use their service without signing up or handing over personal info. You just hop onto their website and get started right away.
They only need a single blockchain confirmation before they process your Bitcoin. The only thing you really have to provide is the wallet address where you want your mixed coins sent.
