Solana (SOL) traded above $140 this week despite a $37 million security breach at South Korea's Upbit exchange. The exchange suspended deposits and withdrawals, relocating assets to cold storage and pledging user reimbursement from company reserves. Franklin Templeton filed Form 8-A with the U.S. SEC to launch a Solana ETF, signaling institutional interest in the ecosystem.

Ethereum is stabilizing around $2,900 amid growing institutional inflows and whale accumulation. CME FedWatch data shows December rate-cut odds have risen above 80%. U.S. spot Ethereum ETFs recorded $96.67 million in net inflows on November 24, with BlackRock contributing $92.6 million.

Dogecoin has retreated to the $0.15 support level, a threshold traders view as pivotal for determining the memecoin's near-term direction.
