1. Weekly Summary
Bitcoin traded in a $4,182 range this week, peaking at $68,044 on October 14 before a hotter-than-expected U.S. Consumer Price Index (CPI) print triggered a 6.1% pullback to a weekly low of $63,862. The asset recovered 4.3% in the final three trading days to end the week at $66,627, for a net 1.2% weekly gain. The week was defined by a tug of war between bearish macroeconomic data that pushed back Federal Reserve rate cut expectations, and bullish institutional catalysts including a new BlackRock Ethereum spot ETF filing and another large Bitcoin purchase by MicroStrategy. Broad market performance was mixed, with Bitcoin outperforming most altcoins as risk appetite remained selective, and total global cryptocurrency market capitalization rose 0.7% to $2.58 trillion. Volatility contracted 34% week-over-week (WoW) for Bitcoin, signaling market participants are holding positions ahead of high-impact regulatory and macro events scheduled for late October.
2. Major Events That Moved Markets
Four key events drove price action this week:
- ●October 15 U.S. CPI Release: Headline CPI came in at 3.7% year-over-year (YoY), 20 basis points (bps) above consensus estimates of 3.5%, while core CPI (excluding food and energy) hit 3.2% vs. 3.1% expected. The CME FedWatch Tool showed the probability of a November rate cut collapsed from 42% to 12% within an hour of the release, triggering a broad selloff in risk assets, with Bitcoin dropping to its $63,862 weekly low in two hours.
- ●October 16 BlackRock Ethereum ETF Filing: The world’s largest asset manager formally submitted a registration statement for the iShares Ethereum Trust, a spot ETH ETF, to the U.S. SEC. The news sparked an immediate 3.2% rally in ETH, and helped reverse broader crypto market losses, as investors priced in higher odds of ETH spot ETF approval in the first half of 2025.
- ●October 17 MicroStrategy Bitcoin Purchase: The business intelligence firm announced it had acquired an additional 1,200 BTC for approximately $79 million, at an average price of $65,830, bringing its total holdings to 198,510 BTC worth ~$13.2 billion. The announcement reinforced institutional demand for Bitcoin, and helped push BTC back above $66,000 by the end of the week.
- ●October 17 MiCA Implementation: The European Union’s Markets in Crypto-Assets regulation went into full effect, creating a unified licensing framework for crypto service providers across 27 member states, reducing regulatory uncertainty for institutional investors operating in the region. The SEC also delayed decisions on 7 pending spot Bitcoin ETF applications until mid-December, a widely expected move that did not trigger a negative market reaction.
3. Price Performance
Bitcoin (BTC)
Bitcoin outperformed most global risk assets this week, with its 1.2% WoW gain beating the S&P 500 (-0.8%) and gold (-0.3%) for the second consecutive week. Its $4,182 weekly range marked the tightest trading window since mid-July, as support at $64,000 held firm despite the post-CPI selloff. Bitcoin’s year-to-date gain now stands at 132%.
Ethereum (ETH)
Ethereum ended the week at $2,387, down 0.7% WoW, underperforming Bitcoin despite the ETF filing news. ETH hit a weekly high of $2,512 immediately after the BlackRock filing, but gave up all gains as macro pressure weighed on risk assets, with profit taking from short-term holders pushing it to a weekly low of $2,219. Ethereum’s YTD gain is 68%.
Altcoins
Performance was highly divergent, with selective upside in sectors tied to AI and layer-1 blockchains, and broad weakness in unproven small-cap tokens:
- ●Large-cap altcoins (top 10 excluding BTC/ETH): Solana (SOL) led gains with an 8.2% weekly rise to $159, driven by a 22% jump in Solana NFT trading volume and the successful migration of the Helium IoT network to the Solana blockchain. XRP fell 2.4% on no material news, while Cardano (ADA) rose 3.1% on increased developer activity.
- ●Mid-cap altcoins (ranked 11–50): Render Token (RNDR) gained 19.3% after announcing a partnership with Nvidia to integrate its distributed GPU network with Nvidia’s AI cloud services, while Arbitrum (ARB) rose 4.7% as total value locked (TVL) on the layer-2 network hit a 3-month high of $18.7 billion.
- ●Small-cap altcoins (ranked below 50): Posted an average gain of 2.1%, but 31% of tokens with market caps under $50 million fell more than 10% on low liquidity, indicating that retail risk appetite remains muted, with investors favoring high-conviction, fundamentally strong projects.
Bitcoin dominance rose 20 bps to 52.1%, while Ethereum dominance fell 30 bps to 17.8%, reflecting Bitcoin’s status as the preferred risk-off crypto asset during periods of macro volatility.
4. Market Sentiment
Sentiment cooled this week but remained firmly in bullish territory, with no signs of broad capitulation:
- ●The Crypto Fear & Greed Index started the week at 78 (Extreme Greed) as BTC approached its 2021 all-time high near $69,000, fell to 62 (Greed) immediately after the CPI selloff, and ended the week at 72 (Greed).
- ●Social sentiment data from Sentiment.io showed that bullish mentions of Bitcoin on X (Twitter) hit 68% of all mentions at the start of the week, fell to 49% (neutral) post-CPI, and recovered to 64% by week’s end after the MicroStrategy and ETF news.
- ●Leverage positioning: Bitcoin open interest (OI) started the week at $27.2 billion, peaked at $29.1 billion in the hours before the CPI print as traders loaded up on leveraged longs betting on an ATH breakout, then fell to $24.8 billion after $1.32 billion of long positions were liquidated in the 4-hour post-CPI selloff. OI recovered to $26.4 billion by week’s end, with the majority of new positions being short positions, a contrarian bullish signal that suggests the market is not overly leveraged to the upside ahead of upcoming catalysts.
- ●Institutional vs. retail sentiment: CoinShares data shows that institutional crypto products saw net inflows of $247 million this week, with 78% of inflows going to Bitcoin products, while retail-focused crypto exchanges saw net outflows of $120 million, indicating that retail investors took profits during the dip while institutions continued to accumulate.
5. On-Chain Insights
Key on-chain metrics signal strong underlying support for current price levels:
- ●Exchange flows: Bitcoin exchange outflows hit 18,200 BTC this week, the highest weekly total since July 2024, as investors moved coins to self-custody in anticipation of long-term price gains. Total Bitcoin held on exchanges now stands at 2.13 million BTC, the lowest level since 2018, reducing the supply of BTC available for sale and creating a supply squeeze dynamic.
- ●Miner activity: Bitcoin miner revenue hit $1.42 billion this week, up 3.7% WoW, driven by higher transaction fees as network activity rose 12% to 392,000 transactions per day. Miners were net buyers of 1,200 BTC this week, breaking a 3-week streak of net selling, a bullish signal that miners expect prices to rise further rather than selling at current levels near the ATH.
- ●Profit and loss metrics: Total realized profits for Bitcoin holders hit $892 million this week, down 41% from the prior week’s $1.51 billion, indicating that there was no mass profit taking during the post-CPI dip, with most long-term holders choosing to hold through the volatility. The share of Bitcoin addresses holding a profit fell from 91.7% at the week’s high to 89.2% at week’s end, still well above the 78% long-term average.
- ●Holder distribution: Addresses holding more than 1,000 BTC (whale addresses) accumulated 4,300 BTC this week, while addresses holding less than 0.1 BTC (retail holders) sold a net 2,100 BTC, continuing the 2024 trend of institutional accumulation and retail profit taking.
For Ethereum, exchange outflows hit 320,000 ETH this week, the highest total since March 2024, as investors front-run expected spot ETF approval. Total staked ETH hit 31.2 million ETH, representing 26.1% of the total supply, a new all-time high, as investors lock up ETH to earn yield ahead of expected price gains.
6. Week Ahead
Three key themes will drive price action in the coming week:
- Macro Data: The U.S. Q3 GDP print on October 23 is expected to come in at 4.1% YoY. A print above 4.5% would likely push rate cut expectations further into 2025, triggering a 3–5% pullback in Bitcoin, while a print below 3.8% would support risk assets. The U.S. core PCE inflation print on October 24, the Fed’s preferred inflation metric, is expected to come in at 3.1% YoY. A print above 3.3% would be bearish for crypto, while a print below 3% would likely push BTC to retest the $68,044 weekly high.
- Catalysts: The SEC has a deadline of October 28 to respond to the Ark 21Shares spot Bitcoin ETF court appeal. If the SEC chooses not to appeal the court ruling that ordered it to review the ETF application, it would remove a major barrier to full spot ETF approval, and could push BTC to a new all-time high above $69,000. The Binance trial is set to begin on October 21, with rumors of a $3–4 billion settlement with U.S. regulators. A settlement in that range would remove a long-standing overhang from the market, while a larger fine or criminal charges against executives would trigger a selloff.
- Technical Levels: For Bitcoin, key support levels are $64,200 (the weekly low and 20-day moving average), followed by $62,100 (the 50-day moving average). Key resistance levels are $68,044 (the weekly high) and $69,044 (the 2021 all-time high). A break above $69,044 would open the door to a move to $73,000, the 1.618 Fibonacci extension of the 2024 rally from $15,500. For Ethereum, key support is $2,250, with resistance at $2,550, and a potential move to $2,700 if ETF momentum continues.
Risk factors include escalating geopolitical tension in the Middle East, which could push oil prices above $95 per barrel, increasing inflation expectations and pressuring risk assets. A sustained drop in spot Bitcoin ETF inflows below $100 million per day for three consecutive days would signal cooling institutional demand, potentially leading to a deeper 10–15% correction.
