Crypto Analyst Warns Quantum Computing Could Trigger Bitcoin’s Worst Bear Market Yet

The post Is Bitcoin Safe From Quantum Computing? CoinShares Data Says Yes For Now appeared first on Coinpedia Fintech News

The quantum computing threat to Bitcoin has been a hot topic recently.

A fresh report from CoinShares finally puts real numbers behind the debate, and the actual risk is much smaller than the headlines suggest.

Can Quantum Computers Actually Break Bitcoin?

CoinShares confirms that quantum algorithms like Shor’s could, in theory, expose private keys from Bitcoin’s ECDSA signature system. But the computing power needed to pull that off does not exist yet and is not coming anytime soon.

Breaking Bitcoin’s secp256k1 curve within one day would need around 13 million physical qubits. For context, Google’s Willow chip currently operates on just 105.

How Much Bitcoin Is Actually at Risk?

Around 1.6 million BTC sits in older P2PK addresses where public keys are visible. But only about 10,200 BTC could realistically cause market disruption if stolen quickly.

The rest is spread across 32,607 separate addresses holding around 50 BTC each. According to CoinShares, cracking those would take millennia, even with the most aggressive quantum progress imaginable.

Modern Bitcoin address formats like P2PKH and P2SH keep public keys hidden behind hashes, which means the vast majority of the supply stays protected.

Should Bitcoin Upgrade Now?

The report urges caution. Rushing into hard forks or unproven quantum-resistant address formats could introduce bugs, burn developer resources, and chip away at Bitcoin’s core values of immutability and property rights.

What Does This Mean for Bitcoin Holders?

CoinShares puts the timeline for cryptographically relevant quantum computers at the 2030s or later. Holders with funds in vulnerable legacy addresses have plenty of time to move them.

The quantum threat is real on paper, but the data says Bitcoin has time on its side.

Fed forecasts only one rate cut in 2026, a more conservative outlook than expected

The post Fed forecasts only one rate cut in 2026, a more conservative outlook than expected appeared on BitcoinEthereumNews.com. Federal Reserve Chairman Jerome Powell talks to reporters following the regular Federal Open Market Committee meetings at the Fed on July 30, 2025 in Washington, DC. Chip Somodevilla | Getty Images The Federal Reserve is projecting only one rate cut in 2026, fewer than expected, according to its median projection. The central bank’s so-called dot plot, which shows 19 individual members’ expectations anonymously, indicated a median estimate of 3.4% for the federal funds rate at the end of 2026. That compares to a median estimate of 3.6% for the end of this year following two expected cuts on top of Wednesday’s reduction. A single quarter-point reduction next year is significantly more conservative than current market pricing. Traders are currently pricing in at two to three more rate cuts next year, according to the CME Group’s FedWatch tool, updated shortly after the decision. The gauge uses prices on 30-day fed funds futures contracts to determine market-implied odds for rate moves. Here are the Fed’s latest targets from 19 FOMC members, both voters and nonvoters: Zoom In IconArrows pointing outwards The forecasts, however, showed a large difference of opinion with two voting members seeing as many as four cuts. Three officials penciled in three rate reductions next year. “Next year’s dot plot is a mosaic of different perspectives and is an accurate reflection of a confusing economic outlook, muddied by labor supply shifts, data measurement concerns, and government policy upheaval and uncertainty,” said Seema Shah, chief global strategist at Principal Asset Management. The central bank has two policy meetings left for the year, one in October and one in December. Economic projections from the Fed saw slightly faster economic growth in 2026 than was projected in June, while the outlook for inflation was updated modestly higher for next year. There’s a lot of uncertainty…
