Bitcoin is private, but not anonymous. Bitcoin uses a pseudonym using a public key (a string of numbers called a bitcoin address) to protect transactions. The public key is not linked to any identifiable information, although in theory it can be used to collect information about a person over time. Sending and receiving bitcoins is like writing under a pseudonym.
In reality, it is pseudonymous because each user has a public address that, in theory, could be traced to an IP address or an exchange account (and, through a proxy, a real identity) through an adequate analysis of the network. The term “pseudonym” refers to the use of a different name on social media, such as a pseudonym or nickname. It is usually used to hide your true identity while maintaining your identity under another name. He is also concerned that if the price of bitcoin skyrockets or goes to the moon, he could be painting a target on his back as a public figure in the Bitcoin space.
Satoshi Nakamoto is the name used by the presumably pseudonymous person or persons who developed Bitcoin, wrote the white paper on bitcoins, and created and implemented the original reference implementation of Bitcoin. To try to achieve that same goal, many bitcoin developers have dedicated their research to improving Bitcoin's privacy. For anyone to make a transaction on the Bitcoin blockchain, you need a wallet that is connected to a Bitcoin node. Bitcoin mixers are solutions (software or services) that allow users to mix their coins with those of other users to preserve their privacy.
According to research by blockchain analysis firm Chainalysis, for example, mixers are mainly used by regular Bitcoin users who simply want privacy. Bitcoin addresses are “anonymous”, but if an address can somehow be linked to a real-world identity, Bitcoin offers no privacy. On the contrary, SW and TDevd wanted to use pseudonyms when they launched Samourai Wallet because the duo was already known in the Bitcoin world by their real names before creating their privacy-focused bitcoin wallet. Bitcoin is often described as anonymous because it is possible to send and receive bitcoins without providing any personally identifying information.
