Ark and Unchained say about one-third of the Bitcoin supply remains exposed to future quantum threats, though the risk is still years away. US investment manager Ark Invest claims that the lion’s share of the Bitcoin supply is already safe from the quantum computing breakthrough, leaving ample warning signals for builders to quantum-proof the rest of the supply. Around 65.4% of the Bitcoin (BTC) supply is not vulnerable to the threat of a quantum computing breakthrough, but about 34.6% of the BTC supply remains at risk, according to a Wednesday white paper published by Ark Invest and Bitcoin-focused financial services company Unchained. This includes around 5 million BTC, or 25% of the total supply, assumed migratable due to address re-use, and 1.7 million BTC, or 8.6% of the supply, assumed lost in P2PK (Pay To Public Key) addresses, the earliest form of transaction script on the Bitcoin blockchain, which locked funds directly to public keys. Another 200,000 BTC (around 1%) is assumed to be migratable due to...

On the 13th day of the US-Israel war against Iran, the conflict appeared to be entering a more volatile phase in which the battlefield could gradually extend beyond conventional air and missile exchanges into attempts to weaken Iran from within; the maritime confrontation in the Gulf continued to tighten pressure on global energy markets and reinforce the centrality of oil flows in shaping the strategic calculations of the belligerents. Reports circulating among Iranian observers and security analysts suggested that Washington and Tel Aviv may now be testing a strategy aimed at fomenting internal dissent while maintaining external military pressure, with recent drone strikes on Basij security infrastructure inside Tehran. This was widely interpreted as an attempt to erode the regime’s internal control mechanisms and probe whether domestic instability could complement the ongoing military campaign. Rescue workers rest next to a damaged residential building in Tehran on March 12, 2026. — AFP The approach bears ...
Crypto ATMs or kiosks are the “lowest-friction extraction channel available to scammers,” said cybersecurity firm CertiK. Crypto ATM fraud surged to $333 million in the US in 2025, with complaints received by the FBI growing 33% in the year as scam networks became more industrialized while tapping into advanced AI deepfake technology. Crypto ATM fraud is one of the fastest-growing financial crime categories in the US, according to cybersecurity firm CertiK in its latest report shared with Cointelegraph on Thursday, explaining that criminal organizations are exploiting the “speed and pseudonymity” of crypto ATMs or “kiosks” to extract funds from victims at an accelerating pace. The FBI recorded more than 12,000 complaints between January and November 2025, also a 33% increase from the prior year. The US accounts for 78% of the world's 45,000 cryptocurrency machines, said CertiK. Read more
New research examines how investor behavior, wallet architectures, and operational security practices determine what genuine self-custody requires in 2026. The foundational promise of cryptocurrency is decentralized, sovereign ownership. But this promise has run into a far more sobering reality, as a lot of funds held on centralized exchanges have been lost over the years. Users have learned the same lesson in different forms: Not your keys, not your coins. Cointelegraph Research’s latest report, produced in collaboration with Trezor, the original hardware wallet, and titled “The Future of Self-Custody: Turning Ownership Into Security,” examines how this realization has reshaped investor behavior. Drawing on survey responses, post-mortem analyses of exchange failures, and a breakdown of modern wallet architectures, the report explains why self-custody should be a defining topic for crypto security in 2026.
