GBTC: Quantum Computing Risk (Rating Downgrade)

  • I am downgrading Grayscale Bitcoin Trust to a 'Sell' due to accelerating quantum computing risks threatening Bitcoin's core cryptography within 5–7 years. GBTC's high 1.5% annual fee and significant tracking error further erode returns, making it unattractive compared to lower-fee alternatives like BlackRock's IBIT. While some argue quantum threats are overblown, I believe the decentralized nature of Bitcoin makes a swift, coordinated upgrade to quantum-resistant security unlikely.
