Why is real-name authentication required to register for a cryptocurrency exchange?

Many users experience strong resistance when registering on cryptocurrency exchanges due to the requirement for identity verification. Including myself, many do not wish for trading platforms to hold personal identity information, especially questioning the necessity of mandatory facial recognition. This contrasts sharply with the anonymity that cryptocurrencies initially advocated—why is real-name authentication still required when purchasing coins on exchanges? Does withdrawing funds from a real-name exchange necessarily lead to tracking of the money flow? Previous cases of ransomware publicly disclosing Bitcoin wallet addresses to evade tracing have further sparked deep reflections on transaction transparency.

When we complete real-name authentication on exchanges to trade Bitcoin, is there a risk of personal information leakage? The registration process requires binding sensitive information such as mobile phone numbers, ID cards, and Google emails; can trading platforms ensure data security? These concerns not only point to the purposefulness of the platform's information collection but also reflect users' worries about the resale of their information. This article will delve into the real-name authentication mechanism of exchanges and explore countermeasures.

Why do cryptocurrency exchanges enforce KYC certification?#

By analyzing typical cases, we can glimpse the regulatory logic. HSBC was fined $1.9 billion for its involvement in money laundering cases linked to drug lords in Mexico and Colombia, and for providing financial services to terrorist organizations and sanctioned countries like Iran and North Korea; Standard Chartered was similarly penalized $132 million by the UK's Financial Conduct Authority for anti-money laundering loopholes, allowing criminal groups to launder $265 billion in illicit funds. These cases illustrate the painful costs traditional financial institutions pay for compliance failures.

Modern cryptocurrency exchanges, as a connection hub between fiat currency and digital assets, also face money laundering risks. If a platform does not implement strict KYC (Know Your Customer) and AML (Anti-Money Laundering) measures, it will face triple pressures:

Heavy penalties from regulatory agencies (e.g., South Korea's Upbit faced a trust crisis due to 600,000 account verifications missing)
Legal risks arising from the inflow of criminal funds
Business losses caused by user attrition

From the platform's operational perspective, a comprehensive KYC system serves as both a firewall against criminal liability and a filter to isolate dirty money contamination. This explains why mainstream exchanges are willing to invest heavily to obtain compliance licenses—OKX obtained the first exchange license in Dubai, Binance is expanding its compliance footprint in multiple countries, and Bitget invested in the licensed Hong Kong institution OSL Group, all highlighting the industry's trend towards compliance.

Is there a risk of leakage of identity verification information?#

The likelihood of exchanges actively leaking user data is extremely low, stemming from two core constraints:

Business Reputation Mechanism: The incident of Upbit's missing certifications led to a sharp decrease in user numbers, confirming the devastating impact of a collapse in trust. Leading exchanges have daily trading volumes exceeding $10 billion; sacrificing long-term credibility for short-term gains is not a rational choice.
Legal Accountability System: Licensed exchanges are directly regulated by local financial authorities, and data breaches will trigger severe penalties.

However, users still need to be vigilant about three types of indirect leakage channels:

Telecommunication Operators: SMS verification may be monitored by operators.
Malicious VPN Services: Free VPNs often have built-in data scraping backdoors.
Phishing Attacks: Fake exchange pages may be used to obtain verification information.

It is recommended to take the following protective measures:

Use a physical SIM card for registration, avoiding virtual operators.
Choose paid commercial VPNs (e.g., ExpressVPN, NordVPN).
Enable hardware security keys (e.g., Yubikey) for two-factor authentication.
Regularly change the login password for exchanges.

For privacy-conscious users, consider tiered usage of exchanges:

Basic Certification: For small fiat deposits and withdrawals.
Anonymous Wallets: Transfer large assets to non-custodial wallets (e.g., Ledger/Trezor).
Mixing Services: Use tools like Wasabi Wallet to enhance transaction anonymity.
