🔥 Bitcoin & Ethereum Market Update – Eyes on Powell Tonight

Bitcoin began to rebound after testing the $82,500 support line during the morning session. However, it faced resistance near $84,677 in the afternoon, leading to a temporary downward pause. It has since dipped to a low of $82,100.

Ethereum is closely mirroring Bitcoin's movement, having touched a high of $1,835 before pulling back and rebounding around $1,876.

Following yesterday’s tariff shock, investor sentiment has become increasingly sensitive and fragile. Tonight’s US Non-Farm Payrolls (NFP) data could bring positive signals for the Federal Reserve, and all eyes are on Fed Chair Jerome Powell's speech at 11:25 PM — his first since the announcement of Trump’s renewed tariff plan.

Interestingly, a long wick candle has just formed, signaling a strong market rebound attempt — reflecting the urgent need for renewed confidence.

💎 Altcoin Revival: One Last Chance?

Innovative projects with real-world use cases, vibrant communities, and strong development teams may emerge as winners.

Weaker altcoins, lacking substance, risk being eliminated.

Approach altcoin opportunities with rationality — always manage risks, avoid blind hype, and conduct solid fundamental research before investing.
