The potential threat of quantum computing to 
Bitcoin's security has been highlighted, with experts warning that current cryptographic methods could be broken by powerful quantum machines. Elliptic-curve cryptography, the backbone of Bitcoin's security, has been known to be vulnerable to quantum attacks for over thirty years.
Despite this longstanding risk, the cryptocurrency industry has yet to implement a comprehensive solution for transitioning to quantum-resistant cryptographic algorithms. This leaves an estimated $2 trillion in digital assets, as reported by Fortune, potentially exposed to future quantum attacks.
The absence of a coordinated migration plan means that as quantum computing technology advances, the risk of cryptographic breaches increases. This development underscores the urgent need for the crypto community to address quantum threats and develop robust security measures.
In the broader market context, Bitcoin's price has shown a slight increase of 0.53% over the past 24 hours, trading at $38,586, while the overall crypto market cap stands at $2.77 trillion. The current Fear & Greed Index of 51 indicates a neutral market sentiment.
The quantum threat to Bitcoin's security highlights a critical challenge for the future of cryptocurrencies. As quantum computing continues to evolve, the industry must prioritize the development and implementation of quantum-resistant cryptographic solutions to ensure the long-term security and stability of digital assets.
Since this brief published about 2 hours ago, Bitcoin (BTC) has moved from $80,586.00 to $80,848.00 — +0.33%.
The chart plots BTC's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution).

Will Bitcoin reach $82,500 in October?
Crowd-implied probability on Polymarket, $91.63K 24h volume, resolves Nov 1 — snapshotted when this brief published (Oct 28 01:05 UTC). A market price reflects what traders collectively expect; it is not a forecast by TLT and will have moved since. View the market ↗
At today's peer-to-peer rate, 1 BTC ≈ ₦111.85M (about $80,848.00), up 1.2% over 24 hours. The naira itself trades about 2.2% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.

Quantum Computing Poses Growing Threat to Bitcoin's Secu — questions & answers
What makes Bitcoin vulnerable to quantum attacks?
Bitcoin relies on elliptic-curve cryptography, which is known to be susceptible to quantum computing attacks.
How much crypto wealth is at risk from quantum threats?
An estimated $2 trillion in digital assets secured by elliptic-curve cryptography could be at risk.
What is being done to address the quantum threat to crypto?
Currently, there is no industry-wide mechanism to transition to quantum-resistant cryptographic algorithms.
How much is 1 Bitcoin worth in naira today?
About ₦111.85M at the live peer-to-peer (P2P) USDT rate, which is what Nigerians typically trade at — equivalent to roughly $80,848.00. The naira price moves with both BTC's US-dollar price and the USDT/NGN rate; use our Bitcoin in naira page for any amount.
