Forget selfies and passports – trade crypto with privacy

Swap without an account

Are you tired of endless KYC (Know Your Customer) requests? Sending selfies, passports, phone numbers, and sometimes even tax documents became the standard. Using most cryptocurrency exchanges has become a privacy nightmare.

When we send our passport and selfies to a cryptocurrency exchange, we have no idea where that data will end up. Companies often monetize user data, and data breaches are so frequent that our personal information can end up on the dark web. As data leaks are so common, we can never be sure that anything we send to those services will remain private.

In the early days of Bitcoin and other cryptocurrencies, privacy was easy to achieve. A decade ago, many reputable exchanges operated without demanding any documentation. Nowadays, there are few of them, and fewer that you can trust your money.

B1exch does not ask for any of those documents and does not attempt to link its users to real‑world identities. The exchange never identify their customers, because they simply do not need to know who they are.

Why privacy is important

Data has become a commodity. Companies monetize user data, often without explicit consent. Loss of privacy can also lead to targeted scams, fraud, identity theft, and long‑term credit damage.

In 1993, cryptographer Eric Hughes published The Cypherpunk Manifesto, a declaration that defined digital privacy as “the power to selectively reveal oneself to the world”.

At the time, the internet was still in its infancy. Today it permeates every aspect of daily life: communication, banking, health care, entertainment, and even civic participation. The manifesto’s core principles have become more relevant than ever.

"When my identity is revealed by the underlying mechanism of the transaction, I have no privacy. I cannot here selectively reveal myself; I must always reveal myself." - Eric Hughes - A Cypherpunk's Manifesto

The blockchain is an open and immutable ledger, which means your transactions are there forever. Once you identify yourself using personal documents in a centralized exchange, your wallet addresses become permanently linked to you.

The good news is that even though the blockchain is immutable, there are some ways to break the link between your coins and you.

Make your bitcoins anonymous

Even after undergoing KYC, there are methods to obfuscate the connection between your coins and your personal data.

You can use mixers or coinjoins. Mixers usually charge a fee between 1-5% and coinjoins will charge less than 1%. Those service will receive your coins and give you back other people' coins. For example, you will send 0.005 BTC and you will receive 0.005 BTC back, minus fees.

Although coinjoin are cheaper then mixers, coinjoin transactions are easily identified in the blockchain. Therefore, those coins are usually "tainted", which means they might have high AML scores.

Another option is to use a good KYC-free exchange, such as b1exch.to. These exchanges will receive your cryptocurrency and give you back other cryptocurrency, which are not linked to you.

Remember that using those services requires trust, because they are centralized. This is why it is important to choose a mixer of exchange with a good reputation.

Tips when evaluating a mixer or exchange

When evaluating a mixer or exchange, always verify their social networks or community-verified reputation scores before transferring funds. Double-check their website URL with social networks links. Those few steps reduce the risk of losing funds to a malicious service.

Remember that all blockchain transactions are final, and once you sent you cannot reverse. Which makes it very important to choose your exchange or mixer wisely.
