Crypto Stock Barometer | Strategy Spends $1 Billion in a Single Week to Increase Bitcoin Holdings, Total Holdings Exceed 780,000 BTC; Bitmine Approves $4 Billion Stock Buyback Plan (April 14)

In a significant move, cryptocurrency intelligence firm Strategy (formerly MicroStrategy) invested $1 billion in a single week to acquire 13,927 Bitcoin, bringing its total holdings to 780,897 BTC. This accounted for the vast majority of the $1.06 billion in net Bitcoin purchases by public companies last week. Other notable corporate developments include Bitmine, an Ethereum treasury company, which added 71,524 ETH to its holdings and announced a massive expansion of its stock buyback program from $1 billion to $4 billion. However, the proposed $1.6 billion SPAC merger for The Ether Machine was terminated due to unfavorable market conditions. In the altcoin sector, Eightco Holdings disclosed it holds nearly 9% of the circulating supply of Worldcoin (WLD) and that its investment in OpenAI constitutes 30% of its total assets. Additionally, Brag House shareholders approved a merger with the Dogecoin Foundation's official entity. The article also covers broader market trends, noting that Bitcoin miners are under profit pressure ahead of the 2028 halving and are shifting towards diversified "infrastructure" business models. Investment firm BlackRock reinstated its overweight stance on U.S. stocks, believing the economic impact of the Iran conflict is manageable.

A Collective Consensus Called Decentralization

The article "A Collective Consensus Called Decentralization" critiques the gap between the ideological promise of decentralization in the crypto industry and its practical reality. While Bitcoin’s original vision proposed a trusted, peer-to-peer financial system free from central control, the author argues that the industry has largely evolved into a performance of decentralization" rather than a true commitment to it. Key examples illustrate this shift: Bitcoin mining is now dominated by a few large mining pools; stablecoins like USDT and USDC—which are centralized, bank-reliant, and allow wallet freezes—account for over 90% of the market; platforms like Hyperliquid operate with centralized decision-making despite decentralized branding; and prediction markets like Polymarket prioritize utility over ideology. The author distinguishes between two layers: the infrastructure layer (prioritizing efficiency and often openly centralized) and the protocol layer (like Bitcoin and Ethereum, which retain structural decentralization). Ultimately, economic incentives drive centralization, as users prefer functional products over pure principles. The piece concludes by calling for honesty: if a project is centralized, it should say so—users can handle the truth but will eventually reject the hypocrisy.

Data Puts Bitcoin At Critical Juncture Following $73,000 Reclaim

Bitcoin has reclaimed the $73,000 level, entering a critical decision point after a 10% weekly gain. Analyst Sminston With notes that Bitcoin is trading near the Power Law estimate of the Cost of Production (CoP) floor at $73,234, indicating fair value. A break below this level could trigger a correction to $60,000, or in a worst-case scenario, drop to $53,000 due to panic selling. Meanwhile, Bitcoin's hashrate stabilizes around 873.19 EH/s, failing to sustain a breakout above 1.2 ZH/s. At press time, Bitcoin trades at $72,709.

Will Quantum Computing Kill Bitcoin and Mining? Is This Alarmist?

The article addresses the recurring concern that quantum computing could break Bitcoin's encryption and disrupt mining. It references a Google Quantum AI white paper from March 2026, which suggests that the resources needed for a quantum computer to crack Bitcoin’s elliptic curve digital signature algorithm (ECDSA) have been reduced by about 20 times. Under ideal conditions, such an attack could theoretically derive a private key from a public key in roughly 9 minutes using 500,000 physical qubits. However, the threat is not immediate. Current quantum processors, like Google’s Willow (105 qubits) or IBM’s Condor (~1,121 qubits), are far from the scale required. The risk primarily targets transaction signatures—especially during the brief window when a transaction is broadcast but not yet confirmed, or when public keys have been historically exposed. It is estimated there is only a 10% probability of a “quantum break” by 2032. The impact on mining is considered negligible. Research indicates that quantum mining would require astronomically high qubit counts and energy—far exceeding entire national grids—making it economically and physically infeasible. The broader solution lies in post-quantum cryptography (PQC). Standards like ML-DSA and SLH-DSA are being developed, and Bitcoin improvement proposals such as BIP 360 aim to reduce quantum vulnerability by modifying transaction structures to avoid exposing public keys. While quantum computing poses a future risk to all public-key encryption systems—not just Bitcoin—the cryptocurrency ecosystem has time to adapt. Upgrades and migration to quantum-resistant algorithms are underway, ensuring the network evolves ahead of the threat.

What does CoreWeave’s $8.5 billion GPU-backed loan mean for Bitcoin mining?

CoreWeave, a former Bitcoin miner that pivoted to AI, has secured an unprecedented $8.5 billion loan using its GPU computing hardware as collateral. This landmark deal highlights the rise of 'ComputeFi' and signals a broader shift away from the volatile 'MinerFi' model. The 2021 Bitcoin mining boom collapsed as BTC prices fell and older ASIC mining rigs lost resale value. In contrast, newer GPU-based miners can be repurposed for AI, offering a more sustainable and profitable path. While some miners like MARA have sold BTC holdings to fund this transition, CoreWeave's GPU-backed loan provides a new financing model. Despite Bitcoin's mainstream adoption, declining miner revenues post-halving and BTC's price volatility are straining the industry. CoreWeave's massive revenue growth in 2025 demonstrates AI's potential, suggesting the pivot to AI among miners will likely continue.

A Once-in-300-Years Event? Independent Solo Miner "Hits the Jackpot," Claims $220K Bitcoin Block Reward Alone

A solo Bitcoin miner with only 70 TH/s of hashrate has successfully mined block 944,306, earning the full 3.128 BTC block reward (approx. $222,000). This miner’s computing power represents just 0.000007% of the total network hashrate, making the probability of such an event roughly once every 300 years on average. The miner used CKpool’s solo mining service, which allows individual miners to work independently rather than in a pool, keeping the full reward minus a 2% fee. This is the 313th solo block mined via CKpool since 2014. Remarkably, this is the second such unlikely event within ten days, highlighting the lottery-like nature of solo mining—where small miners occasionally win big despite extremely low odds.

Cango sells 2,000 BTC in ‘strategic deleveraging’ as Bitcoin miners pivot to AI

Cango, a publicly traded Bitcoin mining company, has sold 2,000 BTC in a strategic move to pay off its BTC-backed loans and reduce debt. The firm raised $75 million from the sale, with some funds allocated to support its diversification into energy and AI infrastructure. This pivot is part of a broader trend among major miners, including Marathon Digital and Core Scientific, who are repurposing their computing resources towards AI ventures. As a result, Bitcoin's global hashrate has declined by 17.4%, potentially lowering network security but creating opportunities for smaller miners to benefit from reduced competition and lower production costs. Despite improving its own mining efficiency, Cango remains vulnerable if Bitcoin's price falls below its production cost of $68.2K.

Bitcoin Needs An Upgrade—But Not Because Of Quantum, Research Argues

Research suggests quantum computing is not an immediate threat to Bitcoin, but an upgrade is still necessary. While headlines highlight quantum risks, analysis shows that deriving private keys from exposed public keys only affects wallets with public keys visible—about 6.26 million BTC (31% of supply), including Satoshi’s coins. Quantum mining is deemed unfeasible due to enormous energy requirements. Current quantum computers are far from breaking Bitcoin’s encryption, equivalent to factoring a 1,300-digit number. The real concern is over-reliance on a single cryptographic system for a $2 trillion network. Upgrades like BIP-360 are in progress to ensure long-term security. Bitcoin price recently rose 6% to ~$72,600.

Bitcoin hashrate drops 77% in Iran: Can stability hold as miners relocate?

Bitcoin's global hashrate remains resilient despite a 77% drop in Iran, where geopolitical strain and energy shortages caused a significant regional mining disruption. The network-wide hashrate stabilized around 960 EH/s, indicating the impact was localized. Miners are relocating to more stable regions like the U.S. and Russia, which now account for 37.4% and 16.9% of the global hashrate, respectively. This redistribution may increase mining concentration and alter future network control dynamics. Meanwhile, miner profitability is under pressure as Bitcoin’s price decline compresses margins, leading to a reduction in miner reserves to 1.8 million BTC. While forced selling creates downward price pressure, stronger miners holding reserves may help limit the downside. The episode highlights Bitcoin’s ability to absorb regional shocks while underscoring ongoing vulnerabilities in energy-dependent mining hubs.

Bitcoin Hashrate Remains Concentrated As US, Russia, And China Hold 65% Share

A new report highlights the continued concentration of Bitcoin mining power, with the United States, Russia, and China collectively controlling 65% of the global hashrate. The U.S. leads with a 37.4% share, followed by Russia at 16.9% and China at 12%. This centralization poses risks, as local disruptions or policy changes can significantly impact the entire network. The global Bitcoin hashrate has declined from 1,083 EH/s in October 2025 to 953 EH/s, influenced by both Bitcoin's price drop since Q4 2025 and a strategic shift among major mining firms toward the more profitable AI datacenter business. While the U.S. saw a minor decline in its share, countries like Kyrgyzstan and Paraguay experienced small gains. Despite these shifts, mining power remains highly concentrated. The report underscores the vulnerability of the network to regional events, citing examples such as China's 2021 mining ban and a U.S. snowstorm that previously led to substantial hashrate reductions. Meanwhile, Bitcoin's price has retreated to around $67,900 after a brief recovery.
