Bitcoin’s security under quantum threat

A leading cybersecurity expert has raised concerns that Bitcoin’s underlying cryptography could be broken within five years. David Carvalho, CEO of Naoris Protocol, warned that quantum computers could soon break the cryptography securing Bitcoin transactions.

He believes the threat could materialise sooner than most anticipate, urging immediate action.

Carvalho pointed to Shor’s algorithm as the core concern. Once sufficiently advanced quantum machines are deployed, they could crack Bitcoin’s defences in seconds.

Roughly 30% of all Bitcoin—around 6 to 7 million BTC—is currently held in wallets with exposed public keys, making them especially vulnerable.

He also referenced major breakthroughs in the field, including Microsoft’s Majorana chip and IBM’s planned release of a fault-tolerant quantum computer by 2029.

With over 100 quantum systems already active and thousands more expected by 2030, Carvalho advised investors to migrate funds to quantum-secure wallets and update their security protocols.

However, Adam Back, CEO of Blockstream and an early Bitcoin contributor, believes the technology is still decades away from posing a real threat. He did acknowledge that future advancements may force even early adopters to move their coins to quantum-resistant addresses.

Trump Media holds $2 billion in Bitcoin assets

Trump Media and Technology Group, backed by $2.5 billion in funding, has acquired around $2 billion worth of Bitcoin as part of an investment plan announced earlier this year. The company behind Truth Social used stock sales and bonds to buy Bitcoin and plans to keep acquiring crypto assets as markets allow.

The announcement followed the US House of Representatives passing three cryptocurrency-related bills during what Republicans and Trump called ‘crypto week.’

Among these, the GENIUS stablecoin bill was signed into law, while two others related to crypto market structure and central bank digital currencies await Senate approval. Bitcoin’s price briefly surged to over $120,000 amid the legislative developments.

Trump’s family-backed crypto firm World Liberty Financial saw its stablecoin governance token more than double last week. Additionally, the president’s memecoin, Official Trump, rose about 10% during the same period, with Trump controlling 80% of its supply through affiliated companies.

In March, Trump signed an executive order proposing a Strategic Bitcoin Reserve and Digital Asset Stockpile for the US. While initially expected to hold seized crypto assets, advisers suggested alternative ideas like revaluing government gold certificates are under consideration.

UK considers Bitcoin sale to plug budget gap

Chancellor Rachel Reeves is reportedly considering the sale of over £5 billion in seized Bitcoin to help reduce the UK’s growing fiscal deficit. The Treasury is under pressure to find alternative revenue sources amid soaring borrowing costs, high inflation, and sluggish growth.

The Bitcoin in question was mostly confiscated in 2018 during a crackdown on a Chinese Ponzi scheme. Since then, its value has risen dramatically, with initial holdings worth around £300 million now estimated at more than £5 billion.

The assets were linked to convicted money launderers, including Jian Wen, and are currently held by UK law enforcement.

While the sale could help avoid tax increases or spending cuts, critics warn of repeating past mistakes. Comparisons have already been drawn to Gordon Brown’s heavily criticised gold sales in the early 2000s, which resulted in billions in missed profits.

There are also unresolved legal concerns about returning funds to victims of the fraud.

Some observers argue the UK should consider holding the Bitcoin as a strategic reserve, in line with countries like El Salvador. Analysts note that the US also sold off seized Bitcoin from 2014 to 2021, missing out on a potential $21 billion gain.

If the UK follows through with the sale, many believe it could prove to be one of the most short-sighted fiscal moves in recent history.

Satoshi Nakamoto becomes 11th richest person in the world

The pseudonymous creator of Bitcoin, Satoshi Nakamoto, is now wealthier than Microsoft co-founder Bill Gates and Dell founder Michael Dell, with an estimated fortune exceeding $130 billion.

The rise in net worth follows Bitcoin’s surge to new all-time highs, gaining over 14% in the past month.

Satoshi’s fortune, believed to stem from 1.1 million BTC mined during Bitcoin’s earliest days, puts him just $12 billion shy of surpassing Berkshire Hathaway’s Warren Buffett, who once infamously likened Bitcoin to ‘rat poison.’

If Bitcoin’s price climbs slightly above $128,000, Satoshi will overtake Buffett on the global wealth list.

While the exact identity of Satoshi remains unknown, theories have pointed to developers such as Hal Finney and Adam Back, as well as public figures like Elon Musk.

None have been confirmed, and the wallets linked to Satoshi have never moved any funds, fuelling speculation he may no longer be alive, or is committed to never selling.

The CLARITY Act defines mature blockchain systems for US regulation

The CLARITY Act seeks to create a clear regulatory framework for digital assets in the US, introducing a ‘mature blockchain system‘ to distinguish commodities from securities.

According to the bill, a mature blockchain system must be free from control by any single person or group. It should also demonstrate decentralised governance, open participation, and transparent operations.

Using the Act’s criteria, an AI analysis conducted with ChatGPT assessed major blockchain networks’ governance models as of July 2025. Key factors considered included decentralisation of decision-making, validator independence, and whether any single entity retained upgrade control.

Based on this evaluation, networks like Bitcoin, Ethereum, Litecoin, Monero, Dogecoin, Tezos, and Cosmos qualify as mature under the proposed legislation.

Some prominent blockchains, such as Solana, Cardano, Polkadot, and BNB Chain, remain under varying levels of central control and do not meet the maturity requirements.

The AI-driven assessment relies solely on publicly available information and serves as a reasoned interpretation rather than a formal regulatory ruling. Experts stress that legal decisions require human oversight and must account for changes in blockchain governance.

Countries build state-level Bitcoin reserves worldwide

Bitcoin is no longer the preserve of tech-savvy investors and crypto enthusiasts. As of mid-2025, more than 460,000 BTC — around 2.3% of the total supply — is held by governments worldwide, according to blockchain data and legal disclosures.

The shift has elevated Bitcoin’s role in global finance, making it a strategic asset for nation-states.

The United States leads the pack with nearly 200,000 BTC, acquired mainly through criminal seizures. Unlike previous administrations, President Trump’s government has moved to consolidate these funds under a federal Strategic Bitcoin Reserve.

China follows closely behind, having confiscated 190,000 BTC from the PlusToken scam, though the fate of much of that stash remains unclear.

Beyond the prominent players, countries like Bhutan have quietly amassed impressive reserves. Using hydropower for mining, Bhutan has reportedly gathered up to 13,000 BTC — worth over $1 billion — equating to more than a third of its GDP.

Meanwhile, the UK holds 61,000 BTC from a money-laundering case, Ukraine used Bitcoin donations during wartime, and Iran requires licensed miners to send their BTC directly to the central bank.

While some nations broadcast their Bitcoin strategy, others operate in silence. From El Salvador’s legal tender experiment to rumours of holdings in the UAE and Bulgaria, the landscape is varied and opaque. Still, one trend is clear: state-level Bitcoin adoption is no longer theoretical.

Governments are actively shaping the future of decentralised money — sometimes loudly, often quietly, but always strategically.

BTC and ETH hold key levels as traders eye next breakout

Bitcoin is holding firm above $108,000, trading at $108,387 as of 8 July. Despite a slight daily dip, longer-term indicators support a bullish trend.

The Relative Strength Index remains neutral at 58.7, while the Stochastic RSI indicates short-term overbought conditions, hinting at a potential pause in momentum.

Shorter timeframes reveal signs of indecision. On the hourly chart, over half of key moving averages lean bearish, and the 4-hour chart shows converging exponential moving averages and tightening Bollinger Bands.

Such patterns often suggest an incoming burst of volatility. Bitcoin faces immediate resistance at $109,700 and $110,000, with a breakout possibly clearing the path to $112,000 or even $137,000. On the downside, traders closely watch support at $107,000 and $105,400, with further risk below $102,000.

Ethereum remains steady at nearly $2,555, trading within a narrow range of $2,500 to $2,600. All major moving averages signal a continued bullish bias, although oscillators such as the RSI (54) and Stochastic RSI (near 85) show signs of exhaustion.

Resistance levels lie between $2,600 and $2,620, with a more decisive breakout potentially driving ETH toward $3,000 or even $4,100. Key support zones are found at $2,500 and $2,440. While short-term caution is warranted, overall, the structure remains optimistic as institutional support strengthens ETH’s position.

Bitcoin takes centre stage as America’s new dream

Changpeng Zhao, former CEO of Binance, has declared that owning Bitcoin could soon replace home ownership as the American dream. Zhao praised the FHFA’s directive for Fannie Mae and Freddie Mac to consider cryptocurrencies in mortgage risk assessments.

The FHFA’s order asks these agencies first to explore using cryptocurrencies as mortgage reserve assets without converting them to US dollars. Prospective homeowners could use crypto holdings on regulated US exchanges as part of their mortgage applications if adopted.

FHFA Director Bill Pulte described the move as historic for cryptocurrency and mortgage industries. He credited President Donald Trump for helping position the US as a global crypto hub.

Meanwhile, during a recent White House press briefing, Trump praised Bitcoin, highlighting its benefits for the US dollar.

India urged to adopt clear Bitcoin strategy

Pradeep Bhandari, spokesperson for India’s ruling Bharatiya Janata Party (BJP), has called for a pilot Bitcoin reserve as part of a strategic move to boost economic resilience. He cites the US’s Bitcoin reserves and Bhutan’s state mining as signs of global finance shifting to crypto.

India’s approach to crypto remains uncertain, with a 30% tax on virtual digital assets but no formal regulatory framework. Under current law, crypto profits are taxed flatly, and a 1% tax is deducted at source on transactions exceeding approximately $115.

Despite this, the lack of regulation has created ambiguity around crypto’s legal status.

Highlighting global developments, Bhandari notes that the US is actively expanding Bitcoin reserves, and three US states have authorised Bitcoin as a reserve asset. He says India’s renewable energy could support a clear Bitcoin strategy that boosts innovation and protects investors.

The BJP spokesperson says a Bitcoin reserve pilot could help India adopt digital assets legitimately and boost its global economic standing with clearer regulations.
