What has been happening this week in the world of blockchain and cryptocurrencies? Current events and background reports in our weekly review.
Selected articles of the week:
Advances in quantum computing continue to gain momentum. New research suggests that the barriers to potential attacks on current cryptographic systems may be significantly lower than previously assumed. This brings closer a scenario that was long considered purely theoretical.
The focus extends beyond Bitcoin to the underlying cryptography on which a large share of digital systems depends. While practical attack capabilities remain limited, recent developments indicate an acceleration in technological progress and a growing reassessment of existing security assumptions. Looking ahead, the implications reach far beyond crypto markets. Affected areas include encryption technologies in the banking system, secure communication protocols and core internet standards. There is no immediate risk in the short term, but the relevance of these developments is set to increase significantly over the medium to long term.

Bitcoin’s Long Path to Quantum Resistance
Recent advances in quantum computing are bringing cryptographic security increasingly into market focus. The computational requirements for a potential attack on Bitcoin and other cryptocurrencies have declined significantly in recent years, narrowing the gap to a more realistic scenario. Early models suggest that such an attack could theoretically be executed within minutes once sufficiently advanced quantum hardware becomes available. At the same time, progress in quantum-resistant cryptography continues, although a full migration is likely to take several years. With NIST standards expected to be implemented by 2035, a clearer timeline is emerging, while Bitcoin’s decentralized governance may slow the transition. For investors, this implies no immediate risk, but a structural factor that is increasingly relevant for long-term valuation.
Quantum computers threaten Bitcoin’s cryptography. BIP-360, NIST standards, and the current timeline – what investors need to know now.
Crypto Market Stuck in Prolonged Extreme Fear
Market sentiment has deteriorated sharply. The Crypto Fear & Greed Index remains deep in Extreme Fear, marking one of the longest pessimistic stretches since 2022, after Extreme Greed prevailed just months ago. The shift is not driven by a single catalyst but by a combination of restrictive monetary policy, geopolitical tensions and a strong US dollar. At the same time, Bitcoin’s correlation with equities has risen, while institutional flows have recently turned negative. Historically, such extreme conditions have often preceded strong recoveries, though timing and magnitude remain uncertain.
The Crypto Fear & Greed Index stands at 8 today, deep in Extreme Fear. It…
Pump.fun and the Token Flood in Altcoins
While Bitcoin faces primarily external risks, the altcoin market is increasingly under pressure from internal dynamics. The main driver is the rapid expansion of token supply. Platforms such as Pump.fun have generated millions of new tokens on Solana since 2024, triggering an unprecedented level of inflation. A large share of all tokens is now concentrated within this ecosystem, while overall quality remains low. The vast majority of projects disappear within a short period, leading to fragmented capital and increasingly short-term allocation rather than sustained investment. The impact is clearly visible in market structure: altcoin market capitalization has declined significantly, new listings are underperforming, and traditional altcoin cycles have shortened considerably. At the same time, elevated token unlocks continue to reinforce structural supply pressure.
Launchpads like Pump.fun have created over 13 million tokens. Data shows how this token flood is structurally reshaping the altcoin market.
Bittensor Trains Largest Decentralized Language Model, Draws Institutional Interest
Not all altcoins are being swept away by the wave of meme tokens. Select projects continue to attract capital through real usage and technological progress. In March, the decentralized AI network Bittensor completed a large-scale language model, highlighting the ability of decentralized systems to compete with centralized approaches. At the same time, institutional interest is rising, with initial ETF filings and larger capital allocations emerging. The strong price reaction of the token suggests that differentiated quality is still being rewarded in the market.
