CoinShares says quantum threat to Bitcoin is real but still years away

Bitcoin faces a theoretical security risk from future quantum computers, but the threat is manageable and not imminent, according to a new research note from digital asset manager CoinShares.

Summary

  • CoinShares says quantum computing poses a real but distant risk to Bitcoin, not an immediate security threat.
  • Only a small share of Bitcoin’s supply, mainly in older addresses, is theoretically vulnerable to quantum attacks.
  • Bitcoin can adopt quantum-resistant upgrades over time, giving the network ample room to adapt.

The firm said concerns that quantum computing could break Bitcoin’s (BTC) cryptography are often overstated, noting that the technology required to carry out such an attack remains far beyond current capabilities.

Even in the most aggressive scenarios, CoinShares estimates that a practical quantum threat to Bitcoin is likely at least a decade away.

Why quantum threat to Bitcoin matters

Bitcoin’s security relies on cryptographic tools that protect private keys and validate transactions. In theory, powerful quantum computers running algorithms such as Shor’s algorithm could one day derive private keys from public keys, allowing attackers to steal funds from certain types of Bitcoin addresses.

However, CoinShares said only a limited subset of Bitcoin is exposed. Roughly 8% of the total supply sits in older “legacy” addresses where public keys are already visible on the blockchain. Even within that group, far fewer coins would be immediately vulnerable in a way that could destabilize the network.

Bitcoin’s core hashing function, SHA-256, is also considered resilient. Quantum computers could speed up brute-force attacks, but not enough to break Bitcoin’s mining or transaction security under realistic assumptions, the report said.

Why the risk is considered manageable

CoinShares emphasized that Bitcoin is not static and has successfully upgraded its cryptography before. The network could transition to quantum-resistant signature schemes through future software upgrades if the threat becomes more concrete.

In addition, holders of older Bitcoin addresses can already protect themselves by moving funds to newer address formats that do not expose public keys until a transaction is spent.

The firm warned against rushing into drastic changes, such as premature hard forks or untested cryptographic schemes, arguing that unnecessary action could introduce bugs or weaken decentralization.

What it means for investors

For investors, CoinShares’ conclusion is straightforward: quantum computing is a long-term engineering challenge, not an existential crisis for Bitcoin today.

The report suggests the market has ample time to prepare, monitor technological progress, and implement safeguards well before quantum computers pose a realistic threat to Bitcoin’s security.

Bitcoin Investors Should Watch These US Economic Signals

Published

on

This Week's Major US Economic Reports & Fed Speakers

Bitcoin traders are heading into a macro-heavy week, with four US economic events expected to shape sentiment across crypto markets.

With Bitcoin trading in a volatile range and macro narratives dominating market psychology, traders are increasingly treating economic releases as short-term catalysts that can trigger sharp moves in both directions.

Which US Economic Signals Should Bitcoin and Crypto Investors Watch This Week?

A Federal Reserve (Fed) governor’s media appearance, key labor-market data, weekly unemployment claims, and January inflation figures could all influence expectations around interest rates and liquidity—two of the strongest drivers of Bitcoin’s price cycles.

Fed Governor Stephen Miran Interview in Focus

Markets will first look to comments from Federal Reserve Governor Stephen Miran, who is scheduled to appear in a podcast interview on Monday, February 9. Ahead of the 5:00 p.m. ET. appearance, there is already mixed sentiment across the crypto community, especially amid broader market caution.  

Some market participants point to Miran’s relatively constructive view on stablecoins, arguing that regulatory clarity and dollar-linked digital assets could indirectly support Bitcoin by strengthening the broader crypto ecosystem and institutional participation.

Others see risk. Speculation that Miran could play a larger role in future Fed leadership has already coincided with bouts of volatility in both precious metals and crypto. This reflects fears that tighter policy could weigh on inflation-hedge narratives.

At the same time, some macro analysts have described Miran as more dovish than many of his peers, citing past arguments in favor of substantial rate cuts to support the labor market.

Any signals in that direction could lift sentiment in risk assets, particularly Bitcoin, which remains highly sensitive to liquidity expectations.

US Employment Report Could Drive “Bad News Is Good News” Narrative

Attention will shift on Wednesday, February 11, to the US employment report, one of the most closely watched indicators of economic health and monetary-policy direction.

Forecasts suggest relatively modest job growth, potentially reaching 55,000 from the previous 50,000. Weaker-than-expected data could paradoxically support Bitcoin. Cooling labor conditions would increase pressure on the Fed to ease policy, potentially improving liquidity conditions for risk assets.

Recent labor-market indicators have already pointed to signs of slowing. Reports of rising layoffs and a slowdown in hiring have strengthened expectations that rate cuts could arrive sooner than previously anticipated.

However, the employment report also carries downside risk. A sharp deterioration in job data could spark broader growth fears, prompting investors to move toward defensive positions. Such an outcome could trigger short-term selloffs in crypto, as seen during previous macro shocks.

Jobless Claims May Reinforce or Challenge the Trend

Thursday’s initial jobless claims release will provide a more immediate snapshot of labor-market conditions. As such, it could reinforce the narrative set by the employment and unemployment reports on Wednesday.

Recent spikes in claims have coincided with risk-off reactions in crypto markets, including liquidation events and rapid price swings. Some traders interpret rising claims as a signal that economic conditions are weakening enough to force monetary easing, a longer-term positive for Bitcoin.

Others warn that in the short term, deteriorating employment data can unsettle markets, especially when liquidity is thin and leverage is elevated.

That dynamic has made jobless-claims releases a growing source of volatility, even though they rarely move markets in isolation.

CPI and Core CPI Seen as the Week’s Decisive Catalyst

The most consequential data point may arrive on Friday, February 13, with the release of January’s Consumer Price Index (CPI) and Core CPI figures.

Inflation data remains the primary driver of Fed policy expectations and, therefore, a key determinant of crypto market sentiment.

Cooler-than-expected readings in recent months have supported risk assets by weakening the “higher for longer” rate narrative.

Another soft inflation print could accelerate expectations for rate cuts in 2026, potentially reinforcing bullish momentum in Bitcoin and strengthening the case for a move toward six-figure price levels over time.

However, sticky or rising inflation would likely have the opposite effect, pushing Treasury yields higher and pressuring speculative assets, including cryptocurrencies.

“If data comes in hot, rates will likely stay higher, and risk assets may struggle. If data cools, rate cut expectations could return, and markets may breathe. This week will tell us what comes next,” remarked analyst Kyle Chasse.

Taken together, the week’s events represent a concentrated test of the macro narratives currently driving Bitcoin: inflation, employment, and the timing of monetary easing.

While long-term adoption trends, such as ETF flows, institutional participation, and stablecoin growth, continue to underpin bullish projections, short-term price action remains closely tied to economic data.

Crypto ETP Outflows Ease as Trading Hits Record $63 Billion

Crypto ETP Outflows Ease as Trading Hits Record $63 Billion

Crypto investment products logged a third straight week of outflows, though the pace of selling eased markedly as digital asset prices steadied after a sharp downturn.

Crypto exchange-traded products (ETPs) recorded $187 million in outflows during the week, a sharp drop from the $3.43 billion seen over the previous two weeks, CoinShares reported on Monday.

The slowdown came as Bitcoin (BTC) fell to its lowest level since November 2024, with the price touching $60,000 on Coinbase last Thursday.

“While flows typically move in line with crypto prices, changes in the pace of outflows have historically been more informative, often signaling inflection points in investor sentiment,” said James Butterfill, CoinShares’ head of research.

Bitcoin ETPs only to post major losses, while XRP leads inflows

Bitcoin investment products were the only ETP group to suffer significant losses last week, with outflows totaling $264.4 million.

XRP (XRP) funds led inflows, attracting $63 million, while other altcoin ETPs, such as those tracking Ether (ETH) and Solana (SOL), posted modest gains of $5.3 million and $8.2 million, respectively.

Spot Bitcoin exchange-traded funds (ETFs) accounted for a large portion of Bitcoin ETP outflows last week, amounting to $318 million, according to SoSoValue data.

ETP volumes hit record $63 billion in weekly trading

Addressing last week’s slowdown in outflows, Butterfill suggested that a “potential market nadir may have been reached,” implying that a possible bottom could have formed for ETPs.

Despite the easing of outflows, last week marked a milestone in trading activity. According to Butterfill, ETP volumes reached a record $63.1 billion, surpassing the previous high of $56.4 billion set in October last year.

Meanwhile, global crypto ETP AUM declined to $129 billion, the lowest level since March 2025, Butterfill noted.

Following three consecutive weeks of outflows, crypto ETPs have lost a total of $1.2 billion year-to-date, compared with $1.9 billion of outflows in Bitcoin ETFs.
