A lot of people still live under the illusion that Bitcoin means anonymity. Spoiler: it doesn’t. The blockchain is transparent as glass. Any analytics firm (like Chainalysis) can map the connections and see where coins came from and where they went. What’s more, they label wallets: “this is an exchange,” “this is a darknet marketplace,” “this is a scammer.” To break that chain and get “complete anonymity,” people use combinations of DEXs and privacy pools.
What is a DEX, and what is it for?
A DEX is a decentralized exchange. Its main selling point is that there are no registrations, no passport-based KYC, and no support agents who can freeze your account “pending investigation.” You just connect a wallet; a smart contract takes your coins and gives you different ones. Nobody knows who you are, why you’re doing it, or where you live.
But there’s a catch. A simple swap on a DEX doesn’t make you invisible. Say you had Bitcoin in wallet A. You swap it for Ether through a DEX, and the Ether goes to wallet B. An analyst can see that Bitcoin left wallet A and Ether arrived in wallet B. The connection is still there because the DEX acts as a bridge that’s visible on both networks. So a DEX is only the first step—the setup for the magic.
How do people move between networks?
Here’s the basic idea. Say you have Bitcoin (BTC) that, for some reason, you need to make invisible. That’s difficult to do directly on Bitcoin, so people exchange it for another asset through cross-chain bridges or DEXs. For example, they swap Bitcoin for Ether (ETH).
At that point, the original connection is somewhat blurred, but Ether is still visible on a public network. Then comes the interesting part:
Ether into Tornado Cash: What is it? It’s a mixer contract on Ethereum. Here’s how it works: you send your ETH to a smart contract, and it gives you a secret cryptographic key in return, like a receipt. Your coins are pooled with the funds of thousands of other users. When you want to withdraw, you create a new, completely clean wallet and use that key to prove to the smart contract—cryptographically, without revealing your identity—that you’re entitled to withdraw. The contract sends you ETH from the pool. Mathematically, it’s impossible to link your original deposit to that withdrawal. The trail is broken.
But here’s an example: Tornado accepts fixed amounts (for example, exactly 1 ETH). If you deposit 10 ETH in ten separate 1 ETH transactions and then withdraw it all at once to a single wallet, you’ve exposed yourself. An analyst can just add up 1 + 1 + 1… You need to withdraw in portions to different addresses.
Bitcoin into ZEC (Zcash): Another route is to swap Bitcoin for ZEC on a DEX and put it into a privacy pool. Zcash calls this a “shielded pool.” When you send coins to a shielded address (a z-address), information about the sender, recipient, and transaction amount is encrypted and concealed using a zero-knowledge cryptographic proof (zk-SNARKs). From the outside, the blockchain looks as if you’ve simply sent money into a black hole. Nobody knows who sent what to whom.
There’s a catch here, too. If you withdraw ZEC from the privacy pool to a transparent address (a t-address), the whole history becomes visible again. Shielding only works while the coins remain in z-addresses.
Straight to Monero (XMR): Or you can skip Ether entirely and swap your Bitcoin directly for Monero. Monero is the cornerstone of crypto anonymity. Ring signatures and stealth addresses work by default, and the trail goes cold. The key is not to make mistakes. Common mistakes include exposing your real IP address when connecting to the network (always use Tor or run your own node), using online wallets, failing to split funds across multiple wallets within the network, or trying to withdraw exactly the same amount of XMR you deposited.
Bitcoin through a mixer: This is a relatively easy route, but it requires preparation and market research. Different mixers use very different mixing algorithms. One might simply send you someone else’s coins, which doesn’t guarantee they’re clean but does break the link to your wallets. Another might send you clean Bitcoin from exchanges, breaking the links. That service will cost more, but the result will be better. It’s definitely worth researching the options before sending funds.
Complete anonymity and beginners’ mistakes
The chain usually looks like this: public wallet => cross-chain DEX => intermediate coin => privacy pool (mixer/Tornado/ZEC/XMR) => withdrawal to a clean wallet.
But there’s one critical detail that trips up beginners. Say you put $10,000 into Monero or Tornado and withdraw $9,995 a couple of days later (the difference went to network fees). That’s a huge red flag! Analysts don’t even need to trace every transaction on the network. They just look at amounts and timing: “Ah, a $10,000 chunk went in, and a $9,995 chunk came out two days later. There’s a 99% chance it’s the same person.”
So the main rule is to split up transactions. Never move the whole amount in one lump. Break $10,000 into ten random transactions of $1,000 each, wait different amounts of time—from hours to days—and withdraw in portions to different wallets. Add random amounts to throw off the patterns.
Another classic beginner’s mistake is linking wallets. Someone sends dirty Bitcoin to a DEX, swaps it for XMR, and withdraws it to clean wallet A. A couple of days later, they send a tiny amount from clean wallet A to an old, exposed wallet to “check whether transactions are working.” That’s it—anonymity killed. The transaction graph can be reconstructed because you linked the clean and dirty trails yourself. Clean wallets need to live separate lives.
In short, if you juggle DEXs skillfully, split amounts, keep clean and dirty wallets separate, use privacy pools, and keep people out of the equation, you can make your funds completely invisible to prying eyes. If anyone has their own ways of doing it more elegantly, I’d love to hear them.
