Crypto Quick Update – Dec 19, 2025 BOJ hikes rates to 0.75% (30-year high), signaling more to come – yen weakens, but risk-off vibes hit markets. BTC ~$86K-87K after tumbling from recent gains. ETH around $2,900. Market volatile amid macro pressures. Watch for potential BTC dumps (historical pattern post-BOJ hikes). Institutional adoption strong long-term, but short-term caution!#bitcoin #CryptoNewss #BTC走势分析 #Ethereum
