Vitalik Buterin warns that quantum computing could pose a serious threat to Ethereum and Bitcoin security by 2028, urging the crypto industry to prepare for a post-quantum future.
Ethereum co-founder Vitalik Buterin has sounded the alarm on quantum computing, stating there’s a nontrivial 20% chance that quantum machines could break current cryptographic protections before 2030, possibly as early as 2028. Both Ethereum and Bitcoin rely on ECDSA (Elliptic Curve Digital Signature Algorithm), which becomes vulnerable once public keys are exposed on-chain. A sufficiently advanced quantum computer could theoretically reverse-engineer private keys, compromising user funds.
Buterin has proposed a contingency plan that includes freezing externally owned accounts (EOAs), rolling back blocks, and migrating assets to quantum-resistant smart contract wallets. This warning highlights the urgency for blockchain networks to integrate quantum-safe cryptography into their long-term roadmaps.
As quantum tech accelerates, crypto security must evolve. The countdown to post-quantum resilience has already begun.

Ethereum is trading at $2,974.66, up 1.58% and showing a modest rebound. Price remains well below the Supertrend resistance at $3,251.11, and MACD is still bearish (MACD: -33.01), with DIF below DEA, indicating weak momentum. The 24h range ($2,895.82–$2,998.52) suggests consolidation near resistance. Despite short-term gains, broader performance is mixed, down 1.16% over the week but only -3.53% over the year, showing relative resilience compared to other majors.
BNB is trading at $892.77, up 2.23% on the day, showing a modest recovery. However, price remains well below the Supertrend resistance at $946.11, and MACD is still bearish (MACD: -5.55), with DIF below DEA, indicating weak momentum. The 24h range ($868.68–$893.75) suggests consolidation near resistance.

XRP se obchoduje za 1,9068 $, což představuje nárůst o 3,59 % a vykazuje známky krátkodobého zotavení. Cena překonala úroveň Supertrend na 1,8761 $, což potvrzuje býčí momentum. MACD je pozitivní (MACD: +0,0051), s DIF nad DEA, což podporuje vzestupný pohyb. 24hodinové maximum na 1,9460 $ označuje další odpor, zatímco objem je silný, přes 125M XRP bylo obchodováno. Navzdory dlouhodobé slabosti krátkodobé momentum podporuje pokračování, pokud se udrží 1,89 $.
Dominance altcoinů se připravuje na svůj další průlom a graf nelže. Po explozivních sezónách v letech 2018 a 2022 všechny znamení ukazují na masivní nárůst altcoinů do roku 2026. Vzestupný kanál je neporušený, MACD právě ukázal další Zlatý kříž a momentum se buduje. Tohle není hluk, je to nastavení pro plnohodnotnou rotaci z BTC do vysoce beta altcoinů. Pokud se historie opakuje, další sezóna altcoinů by mohla být větší, rychlejší a divočejší než cokoliv, co jsme viděli.
Crypto Resilience vs. Banking Limits: CZ’s Davos Statement
At the World Economic Forum in Davos, Binance founder Changpeng Zhao (CZ) delivered a pointed critique of traditional banking infrastructure, highlighting the resilience of crypto platforms under stress. Speaking on the robustness of Binance’s operations, CZ revealed that the exchange processed $7 billion in withdrawals within a single day and $14 billion over the course of a week, without disruption or liquidity issues.
“I don’t know of any bank that can handle that,” CZ stated, underscoring the limitations of legacy financial institutions when faced with sudden outflows. His remarks reflect a broader narrative emerging from the crypto sector: decentralized and digital-native platforms are increasingly demonstrating operational agility and scalability that traditional systems struggle to match.
The statement also serves as a subtle reassurance to market participants following periods of volatility and regulatory scrutiny. By emphasizing Binance’s ability to meet extreme liquidity demands, CZ reinforces the platform’s credibility and the evolving maturity of crypto infrastructure. As institutional interest grows, such performance metrics may become key differentiators in the race to define the future of finance.
Bitcoin is trading at $87,622.01, down 1.74% and showing continued weakness. Price remains well below the Supertrend resistance at $94,048.84, and MACD is sharply bearish (MACD: -773.41), with DIF far below DEA, confirming strong downward momentum. The 24h range ($86,074–$89,268) reflects tight consolidation, but broader performance is negative, down nearly 8% over the week and 24% over 90 days. A break below $86,000 could trigger further downside toward $83,500.
