Ledger CTO Charles Guillemet highlighted two recent cryptographic breakthroughs that could pose future risks to Bitcoin's security. One involves a new subexponential algorithm that might theoretically solve elliptic-curve cryptography problems more efficiently, though it currently poses no immediate threat to Bitcoin's widely used curves. The other is a significant improvement in quantum computing attacks, reducing the estimated resources needed to break Bitcoin's cryptography, but such quantum computers do not yet exist. These findings underscore the ongoing need to monitor and evolve cryptographic protections for cryptocurrencies.
While Ledger's CTO warns about future cryptographic threats to Bitcoin, the cryptocurrency currently trades at Rp1.392.721.242 on Pluang, down 3.58% over the past day as of Oct 31, 2026 04:21 WIB. Bitcoin's circulating supply is near its maximum at 20.1 million out of 21 million BTC, with a market cap of Rp28.011,03 trillion. Despite the concerns, Pluang users show a balanced sentiment with 58% buying and 42% selling, holding their investments for an average of 112 days.
Bitcoin is on track for its second consecutive negative October, down about 8.4% as of late October 2026, trading near $76,000. This breaks a long-standing seasonal trend where October usually sees gains, with an average 19% rise since 2013. The pric...
Bitway (BTW) led losses among the top 90 cryptocurrencies by dropping 26.52% to $1.20 on October 30, with 77 out of 90 major cryptocurrencies declining. Other notable drops included Venice Token (-14.41%), Pearl (-13.80%), and Injective (-12.43%). Me...
Tether reported $4.5 billion in profit for the first nine months of 2026, but its USDT reserve buffer grew by only $1.66 billion to $7.95 billion, now smaller than its $8.37 billion Bitcoin holdings. This exposes USDT holders to risks from Bitcoin an...
