The final week of October 2025 (October 21–26) in the cryptocurrency and blockchain industry was defined by market recovery, a massive institutional pivot, and regulatory maturation in major global economies.
Bitcoin miner stocks pivot to AI
Perhaps the most significant long-term structural news of the week was the massive shift by publicly traded Bitcoin mining companies toward Artificial Intelligence (AI) data center operations. On October 21, the shares of major miners, led by CleanSpark, surged after announcing plans to dedicate substantial portions of their high-performance computing infrastructure to AI.
Miners, which operate large-scale data centers for the energy-intensive process of securing the Bitcoin network, are now looking to monetize their underutilized infrastructure by providing computing power for AI models, a service in extremely high demand.
Market recovery after record liquidation event
The week opened with the crypto market showing signs of stability and a modest rebound, following what analysts described as the biggest single-day crypto liquidation event in history in the preceding days.
Bitcoin (BTC) recovered to trade back above the $110,000 mark, showing resilience after briefly touching lows around $101,000. Ethereum (ETH) also held steady.
The recovery was largely attributed to two factors: renewed institutional inflows into the U.S. spot Bitcoin and Ethereum ETFs, and positive anticipation around potential Federal Reserve interest rate cuts at the end of the month, which generally favors risk assets like crypto.
Japan mulls sllowing local banks to hold and trade crypto
News broke on October 21 that Japan’s Financial Services Agency (FSA) was considering reforms to allow domestic banks to buy, sell, and register as crypto exchanges.
Current FSA guidelines largely ban domestic banks from holding digital assets due to volatility concerns. A reform would open the Japanese market to traditional financial institutions (TradFi), allowing them to offer broader access to digital assets for retail traders and potentially leading to massive new capital inflows and improved market stability under regulated entities.
Solana co-founder teases new on-chain perpetual DEX
Amidst a flurry of DeFi innovation, Anatoly Yakovenko, co-founder of the Solana blockchain, was rumored to be designing a new on-chain perpetual decentralized exchange (DEX) named “Percolator.”
While the initial speculation was that the project was a full-scale launch, it was later clarified to be an experimental, AI-generated proof-of-concept. Regardless, the discussion highlighted the relentless focus of top blockchain developers on solving key DeFi challenges, particularly in the realm of perpetual futures trading, which remains a cornerstone of on-chain activity. The emphasis on new, high-performance DEX architectures shows the continuing evolution of decentralized finance.
Ethereum Foundation migrates $650M+ treasury to safe multisig
The Ethereum Foundation completed the migration of its substantial treasury—over 160,000 ETH, valued at approximately $650 million—to a Safe{Wallet} (formerly Gnosis Safe) multisig contract.
A multisignature wallet requires multiple pre-approved keys to authorize a transaction, offering a superior layer of security compared to a single-signature wallet.
This move enhances the security and transparency of the Foundation’s vast holdings. For the wider ecosystem, it reinforces the best-practice standard for securing large institutional or communal digital asset treasuries, lending credibility to the security model of mature DeFi tools.
