Cryptocurrency

Introduction

Cryptocurrency emerged in 2009 with Bitcoin, promising financial privacy and freedom from traditional banking systems. While blockchain technology offers transparency, this very transparency can compromise privacy as transactions are permanently recorded and publicly visible. The challenge lies in balancing the benefits of decentralized finance with the need to protect personal financial privacy.

Providers

Coinbase

The largest US-based exchange collects extensive user data for regulatory compliance. In 2021, Coinbase faced criticism for its new privacy policy allowing user data sharing with government agencies. The platform requires full identity verification and tracks all transaction history.

Binance

The world’s largest crypto exchange has faced regulatory scrutiny worldwide. In 2022, Binance enhanced its KYC requirements after multiple regulatory warnings, requiring more personal data from users. The platform tracks and stores detailed trading patterns and withdrawal history.

Ledger

A leading hardware wallet provider that experienced a major marketing database breach in 2020, exposing customer names, addresses, and phone numbers. While the crypto assets remained secure, the incident highlighted risks in peripheral systems.

Metamask

The popular Web3 wallet collects user data including IP addresses and transaction history. In 2022, it updated its privacy policy to disclose that it logs user IP addresses during transactions, raising concerns about privacy implications.
