Bitcoin (BTC) 
$87,175.01 The debate around quantum computers has reignited and the long-term durability of Blockchain security has come under the spotlight. Co-founder and Security Director of self-custody solution Casa Jameson Lopptried to calm short-term panic by saying that the current level of technology is far from breaking Bitcoin’s cryptography. Still, according to Lopp, it will take years for the network to prepare for the post-quantum era, and time for preparation is running out.
Quantum Threat to Bitcoin Seems Limited for Now
Jameson Lopp, X In his post on his account, he emphasized that quantum computers do not pose a short-term risk for Bitcoin. researchers quantum Stating that he will continue to monitor the progress in informatics, Lopp said that the current hardware and practical capacity are the ones used by Bitcoin. cryptographyHe is of the opinion that it has not reached the level to break .
The point that Lopp really emphasized was the length of the preparation time. Bitcoin’s evolution to a quantum-resistant architecture will require carefully designed protocol changes. However, a migration process that is difficult to coordinate, such as moving funds across the network to new structures, will also come to the fore. Lopp stated that such a transformation could take 5 to 10 years and shared the message, “We need to hope for the best and prepare for the worst.”
asset management company Grayscale also drew a similar framework in the report it published last week. According to the report, sufficiently powerful quantum computers could theoretically surpass existing cryptographic systems, but Grayscale does not see the emergence of these capabilities in the short term and estimates that the threshold may extend beyond 2030. While the company acknowledges that post-quantum cryptography research and network preparations may accelerate, from an investment perspective it is expected to start in 2026. cryptocurrency He stated that he does not expect a significant impact on valuations and market performance.
Why Are Warnings Getting Harder?
Ethereum is on the more cautious side 
$2,953.47co-founder of Vitalik Buterin It is located. Quantum computing may be a more imminent risk to blockchain cryptography than often underestimated, Buterin warns in your opinion. He also stated that the probability of quantum computers breaking existing cryptographic systems before 2030 is 20 percent. This ratio moves the discussion out of the “distant future” category and into the planning calendar.
Founder of quantitative Bitcoin fund called Capriole Charles Edwards He also shared the view that ignoring the risk could lead to serious consequences. According to Edwards, a harsh bear market could be a trigger for the community to take threat perception seriously and accelerate network updates. Edwards suggested that if Bitcoin does not implement a quantum-resistant solution by 2028, the price may fall below $ 50,000, and the decline may continue until the problem is solved.
While Edwards stated that the need for urgent action could be felt starting next year, he said that the delay could pose the risk of “the biggest bear market in Bitcoin history” and FTX He claimed that previous crises such as these could be overshadowed.
