A new report warns that Bitcoin and other digital assets secured by elliptic curve cryptography could become vulnerable to quantum attacks within the coming years, with the so-called “Q-Day” potentially arriving as early as 2030.
According to the report, more than $3 trillion worth of crypto assets may face increasing security risks within the next four to seven years if quantum computing capabilities advance faster than expected.
The report noted that migrating Bitcoin to quantum-resistant security infrastructure could take between five and more than 10 years due to the need for coordinated action among users, exchanges, custodians, miners, and other participants across the ecosystem.
Experts believe the challenge extends beyond developing new cryptographic solutions and includes executing a large-scale technical transition without disrupting network stability or compromising digital asset security.
