Bitcoin (BTC) 暴跌后投资策略：2025年12月抄底指南与风险管理（交易者实战）

Circle has launched Digital Asset-Backed Borrowing for eligible Circle Mint LLC customers, creating an integrated institutional workflow that allows Bitcoin holders to access USDC liquidity without first selling their BTC. Launched on September 21, 2026, the service allows eligible customers to deposit BTC, mint Circle Wrapped Bitcoin (cirBTC), move that tokenized collateral through a wallet they control into supported third-party lending markets, and receive borrowed USDC directly in Circle Mint. The workflow is available across Arc and Ethereum, with Morpho-supported markets included at launch

Altcoin trading volume has surged relative to Bitcoin, with recent spot activity approaching four times BTC spot volume and reaching its strongest relative level since September 2025. The shift is notable because it is occurring alongside broader market participation rather than an obvious surge in leverage. Glassnode reported that 72.5% of the altcoins it tracks outperformed Bitcoin over the latest week, while overall exchange spot volume had more than doubled from its August low. At the same time, altcoin perpetual open interest measured in coins had barely increased over the previous 30 days, suggesting that the latest rotation has been driven more by spot-market participation than by a rapid build-up of leveraged derivatives positions

Hong Kong is expanding regulated access to Solana with the listing of the Pando Solana ETF on October 13, 2026. The product, trading under stock code 2831 on the Hong Kong Stock Exchange, becomes the market’s second spot Solana ETF rather than its first. ChinaAMC launched its own Solana ETF on October 27, 2025, giving investors almost a year of real-world data against which the new product can be judged. That history changes the key question. The launch is no longer simply about whether regulators will permit a Hong Kong Solana ETF. It is about whether a second issuer can deepen liquidity, attract incremental capital and turn regulated SOL exposure into a meaningful institutional allocation channel.
