For the week ending September 22, 2025, the crypto market experienced a mild correction, with total capitalization dipping 0.8% to $4.17 trillion, driven by profit-taking after Bitcoin's surge to $124,500 on August 14.

Bitcoin (BTC) traded around $115,000-$116,000, down 0.07% to $115,950, while Ethereum (ETH) fell 1.93% to $4,500, amid anticipation for the Fed's rate cut on September 17 and upcoming events like EDCON Osaka.

Informed by trusted sources like CryptoNews, CoinDesk, and The Block, this digest highlights top stories, trends, and implications. Whether you're HODLing BTC or staking ETH, stay informed amid 2.1% PCE inflation and a 4.00-4.25% federal funds rate.

1. Crypto Overview: Key Highlights for the Week

The market consolidated after recent highs, with BTC and ETH dipping amid Fed rate cut anticipation and token unlocks, but positive sentiment from stablecoin growth and ETF inflows provided support.

• Market Dip: Total cap fell 0.8% to $4.17 trillion, with 8 of top 10 coins down; BTC at $115,950 (-0.07%), ETH at $4,500 (-1.93%), BNB at $994.72 (+0.7%).

• Fed Rate Cut: September 17 cut to 4.00-4.25% boosted risk appetite; BTC briefly hit $116,450 before pulling back.

• Events & Launches: EDCON Osaka (September 16-21) kicked off with Ethereum updates; Bitlayer (BTR) launched on Binance September 18.

2. Bitcoin (BTC) News: Steady Amid Correction

BTC held above $115,000 despite a broad market dip, buoyed by Fed easing and ETF inflows, but profit-taking capped gains.

• Price Action: BTC traded $115,000-$116,000, down 0.07% to $115,950 after peaking at $116,450; market cap $4.17 trillion (-0.8%).

• ETF Flows: Spot ETFs saw $1.17 billion net outflows August 18-22, but inflows resumed with Fed optimism.

Key Story: BTC's pullback to $115,950 post-Fed cut reflects profit-taking, but Tom's $150,000 year-end call and reserve rumors signal bullish Q4.
