The debate over Bitcoin self-custody versus custodial services has intensified, with recent actions by major cryptocurrency exchanges like Coinbase and Kraken sparking controversy. These exchanges have flagged large USDC transfers, leading to discussions about user protection versus censorship. Proponents of self-custody argue that true ownership of cryptocurrency requires control over private keys, encapsulated in the phrase 'Not your keys, not your crypto.' Critics, however, question whether users are prepared for the responsibilities of absolute control. The increasing centralization in the cryptocurrency space, particularly in Web3, has also raised concerns about potential large-scale hacks, with some warning of the 'biggest hack in history.'
