Nic Carter, a prominent figure in the 
Bitcoin community and co-founder of Castle Island Ventures, has issued a warning about the growing threat of quantum computing to Bitcoin. He predicts that this threat will become significant within the next 10 years.
Quantum computing, with its potential to solve complex mathematical problems much faster than classical computers, could theoretically break the cryptographic algorithms that underpin Bitcoin's security.
While Bitcoin's current cryptographic protocols are considered secure against classical computing attacks, the advent of powerful quantum computers could change this landscape. This potential threat underscores the need for ongoing research and development in quantum-resistant cryptographic techniques.
Despite these concerns, the Bitcoin market remains resilient, with a market cap of $1.62 trillion and a 24-hour price increase of 1.09%. The overall crypto market is also performing well, with a total market cap of $2.77 trillion.
The Fear & Greed Index currently stands at 48, indicating a neutral market sentiment. This suggests that while the quantum threat is a long-term concern, it has not yet significantly impacted market sentiment.

At today's peer-to-peer rate, 1 BTC ≈ ₹8.35M (about $80,809.00), up 1.4% over 24 hours. The rupee itself trades about 8.4% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.
