What is KYC in Bitcoin?

KYC, short for 'Know Your Customer,' is a banking regulation designed to prevent money laundering, fraud, and other illicit activities by requiring financial institutions to verify the identity of their clients. Typically, it involves three components: customer identification program (CIP), customer due diligence (CDD), and enhanced due diligence (EDD).

The customer identification program involves sharing your identification documents and personal details such as date of birth and address with the financial institution. Customer due diligence is used to verify a client's identity and evaluate their risk profile, and enhanced due diligence is used for "higher risk" clients where additional information may be necessary.

What is the purpose of KYC in Bitcoin?

Given the proliferation of financial institutions in the digital asset space, KYC has become commonplace when purchasing Bitcoin. All centralized exchanges are required by law to implement proper KYC procedures, however, there are many decentralized and peer-to-peer (P2P) methods of obtaining Bitcoin in a KYC-free manner.

In the context of Bitcoin, KYC involves collecting and verifying personal details such as identification documents, addresses, date of birth, and sometimes financial details before a user can purchase Bitcoin on a given platform. This process helps exchanges comply with legal requirements and ensure the integrity of transactions on their platforms. However, KYC measures can also impact user privacy and anonymity, key principles for many investors.

Why do people avoid KYC?

Many individuals avoid KYC procedures because they value their privacy and embrace Bitcoin's peer-to-peer philosophy. KYC requires users to divulge significant personal information, which many view as an intrusion of their privacy and contradictory to the fundamental principles of Bitcoin. They prefer to transact directly with others (P2P) without intermediaries, preserving financial privacy and autonomy over their financial activities.

Additionally, fears exist over potential government overreach, reminiscent of historical events like Executive Order 6102 in the United States, which mandated the confiscation of privately held gold under threat of imprisonment. By avoiding KYC, thus severing the tie between one's identity and digital asset holdings, individuals believe they can reduce the risk of similar government actions targeting Bitcoin. This thought process also applies to those who wish to improve overall privacy about their bitcoin holdings, lowering risks of being targeted in a hypothetical $5 wrench attack.

In summary, rather than participating in illegal activities, many users take a non-KYC approach for their privacy, security, and to align with the vision of Bitcoin as a tool for financial freedom and independence. 

What is the drawback of KYC?

The primary drawback of KYC is the significant risk to user privacy and security. KYC procedures require individuals to divulge significant personal information which is then stored in centralized databases. These databases can become prime targets for hackers, creating honeypots of sensitive data, that if breached, can lead to identity theft, financial fraud, and other negative consequences. High-profile data leaks from large financial institutions have highlighted these vulnerabilities. Consequently, many people prefer to engage in P2P transactions and use non-custodial services that do not require KYC.

Does a Bitcoin wallet need KYC?

A Bitcoin wallet itself does not inherently require KYC procedures. The need for KYC arises when a wallet is integrated with services provided by financial institutions or centralized exchanges mandated by law to comply with regulatory measures.

In contrast, non-custodial Bitcoin wallets, which allow users to maintain full control over their private keys and funds, do not require KYC. These wallets are open-source software tools that facilitate the self-sovereign capabilities of Bitcoin, allowing users to send, receive, and store Bitcoin without needing to share personal information. By using KYC-free and non-custodial wallets, individuals can engage in P2P transactions directly, preserving their privacy and reducing security risks and financial surveillance.
