Bitcoin Exchanges at Forefront of Quantum Computing Risk

The threat of quantum computing to Bitcoin's security has long been a topic of debate among experts. However, a recent study by Glassnode sheds new light on this issue, revealing that cryptocurrency exchanges are at the forefront of the risk.

According to the data, around 30% of Bitcoin's circulating supply is held in wallets with publicly visible cryptographic keys. This exposure is primarily due to poor wallet management decisions and legacy infrastructure, rather than a fundamental flaw in the protocol itself.

The largest contributor to this exposure is operational risk, which accounts for around 4.12 million Bitcoin. Exchanges account for a significant portion of this risk, holding around 1.66 million exposed Bitcoin, equal to more than 8% of the total issued supply.

The data also reveals that crypto exchanges are not alone in their exposure. Traditional Wall Street institutions and sovereign wallets have varying levels of exposure, with some showing much higher concentrations of publicly visible keys.
