Yearn Finance suffered a security breach that drained approximately $9 million from its yETH infrastructure. Attackers exploited a vulnerability in the yETH token contract, enabling unlimited token minting without collateral and draining liquidity from a staked Ethereum derivatives pool. The protocol confirmed the yUSND pool and Nerite's vaults remained unaffected.

Arthur Hayes, co-founder of BitMEX, predicts cryptocurrency-style perpetual futures contracts will overtake traditional stock exchange products for equity trading. He forecasts equity price discovery will shift to 24/7 perpetual markets on crypto platforms by 2026. CBOE and SGX are preparing to launch their own perpetual products by end-2025, according to Hayes.

Binance's XRP reserves have dropped to approximately 2.7 billion tokens after roughly 300 million XRP were withdrawn since October 6. Data show investors are transferring holdings to private wallets, reducing available supply on the exchange. XRP currently trades near $2.19, showing mixed short-term performance despite the sustained withdrawal activity.

South Korean cryptocurrency exchange Upbit suspended all deposit and withdrawal operations on November 27 after detecting an unauthorized transfer of approximately $38.5 million in digital assets. The breach affected multiple Solana-based tokens, including SOL, USDC, BONK, and others. The exchange has pledged to cover all customer losses using its own reserves, with services to resume after completion of security reviews.

Japan's Financial Services Agency has finalized amendments transitioning digital asset oversight from the Payment Services Act to the Financial Instruments and Exchange Act. The reforms mandate stricter disclosures, custody protections, and fraud prevention measures as cryptocurrencies gain mainstream adoption. Japan records 20,000 to 40,000 unique active Bitcoin addresses daily, but analysts note the country's substantial household wealth could drive significant institutional demand through ETFs and regulated investment vehicles.

Tokyo-based Metaplanet Inc. recorded an unrealized loss of approximately $651 million on its 30,823 BTC holdings as of November 26, according to analyst Shanaka Anslem Perera. The company acquired its position at an average cost of $108,036 per coin, while Bitcoin traded around $87,500. Metaplanet's stock declined 81% from June through late November, with shares trading below the value of underlying Bitcoin assets. A shareholder vote scheduled for December 22 will determine whether approximately ¥21.25 billion in capital from a perpetual preferred equity instrument proceeds forward.

Bitcoin fell to around $79,500 in mid-November before recovering toward $88,000, but wallets holding over 1,000 BTC continue selling. Mid-sized holders with 10–1,000 BTC accumulated during the decline, while futures liquidations reached levels comparable to the FTX collapse in November 2022.

Bitcoin dropped from approximately $107,000 to near $81,000 between November 11 and November 21, triggering widespread market turbulence. Data show Ethereum experienced comparatively restrained losses due to its post-Merge staking mechanics and token burn features. These supply dynamics reduced available tokens during the correction, cushioning the decline relative to historical patterns.

Short-term Bitcoin holders capitulated as BTC declined to test $80,000 support, marking a 36% drop from its October peak. On-chain data show investors holding for under 155 days shifted sentiment from positive to negative, a pattern previously observed near local market bottoms within the current cycle.
