Bitcoin fell 4.1% this week, trading below $83,000, as US spot Bitcoin ETFs recorded a massive $484.9 million outflow on Wednesday, marking the worst single-day ETF loss since June 25. The decline came in October, a month that has historically been favorable for Bitcoin, commonly referred to as “Uptober” among traders.
Key support levels face renewed pressure
According to CoinGecko data, Bitcoin hit lows of $80,427 in the past week and is currently just under $83,000. Market participants remain cautious as the cryptocurrency failed to maintain momentum above $87,000 at the week’s start. Analysts noted that this failure stemmed mainly from aggressive futures positioning rather than substantial spot demand.
On the prediction platform Myriad, users estimate a 79% probability that Bitcoin will end the week above $82,000, while only assigning a 28% chance to prices climbing past $84,000. The $83,000 level is being closely watched because it aligns with the average ETF cost basis and a prior technical threshold.
The $83,000 region is significant, combining the average ETF cost with previously established technical resistance, and has been tested several times in recent weeks, according to Luke Deans, Senior Research Associate at Bitwise Europe. He added that reactions to movements around this level could help determine whether lower support targets will soon be in play.
Deans noted if Bitcoin fails to recover and hold above $83,000, attention will turn to support at $77,000, which on-chain metrics suggest is a notable acquisition level. Other technical measures highlight additional support at $74,000 and at the 200-day moving average near $72,000, providing further benchmarks for possible downturns.
Ananda Banerjee, Founder and Principal Quantitative Researcher at Charlie Quant Lab, also pointed to $77,000 as a significant on-chain support level, while Deans emphasized the $72,000 to $77,000 range as a key transition area for Bitcoin’s price structure.
If Bitcoin successfully holds these levels, previous resistance zones could convert to support, potentially reinforcing the asset’s current market structure. However, failing to defend this range, Deans stated, may weaken the existing risk-on environment for Bitcoin investors.
Spot ETF demand and macro data under scrutiny
Analysts at Bitfinex highlighted that lower spot volume has weighed on price action. US spot Bitcoin ETFs attracted $241.1 million between September 28 and October 2, a figure significantly below the previous week’s $2.39 billion inflow. With the average ETF investor now at breakeven for the first time since January, analysts report that inflows historically slow at such levels.
Market strategists say Bitcoin’s trading range remains between $84,000 and the yearly open at $87,722. The upcoming September CPI announcement, along with potential changes in ETF inflows, could shift this range in the coming days. On Wednesday, Bitcoin ETFs registered a one-day outflow of $484.9 million, led by BlackRock’s IBIT and Fidelity’s FBTC, followed by an additional $244 million withdrawn Thursday. Recent outflows have erased nearly 81% of inflows seen in the two previous weeks, though total net inflows across these funds still stand at $57.8 billion.
Jake Kennis, Senior Research Analyst at Nansen, indicated that while October has historically delivered a median return of about 14% for Bitcoin, ultimately liquidity, positioning, macro conditions, and fundamentals remain the market’s primary drivers.
The ongoing volatility is a strong reminder of how quickly market conditions can change, influenced by macro data, policy decisions, or major ETF actions. In a market where a single Fed decision or a sudden altcoin listing can shift momentum instantly, traders are beginning to use privacy-first apps like CryptoAppsy for integrated charting, news, and portfolio monitoring—offering real-time data and price alerts without requiring an account.
While some experts hesitate to declare the end of “Uptober” based on one week, most warn that investment decisions should focus on underlying fundamentals rather than seasonal patterns. Liquidity, ETF flows, and macroeconomic developments remain the dominant factors shaping Bitcoin’s path this month.
