Bitcoin was trading around $84,800 on Sept. 27, 2026, holding close to the $85,000 mark after a week of heavy buying through U.S. spot Bitcoin exchange-traded funds. The largest cryptocurrency gained 0.88% over 24 hours, slightly trailing a 1.03% advance across the broader crypto market.
The price action leaves traders focused on two near-term signals: whether BTC can clear resistance at $86,000 and how the market reacts to the Sept. 30 U.S. inflation report.
ETF inflows provide support
U.S. spot Bitcoin ETFs attracted about $2.4 billion during the five trading days ended Sept. 25, according to SoSoValue. That was the strongest weekly inflow of 2026 and marked a shift back to net buying after a period of outflows.
Bitcoin’s 30-day correlation with the S&P 500 reached 95%, underscoring how closely the asset has tracked broader risk sentiment and interest-rate expectations. BTC also remained above its key daily moving averages, and its MACD stayed positive. Those technical signals, however, do not show how much of the move was driven specifically by ETF demand.
Miner reserves and hashrate decline
Miner reserves fell by 1,530 BTC in the week to about 1.193 million BTC, according to CryptoQuant, which tracks wallets tied to miners and mining pools. A decline in reserves does not by itself confirm sales; coins may be sold, moved into custody, or redirected for other uses.
The network’s seven-day average hashrate dropped to roughly 915.8 exahashes per second on Sept. 26, a three-week low. Hashrate estimates can fluctuate because of block timing, power availability, and changes in active mining equipment. Mining continued during the decline.
Bitcoin’s Puell Multiple rose by 0.24 during the week to 1.13. The metric compares daily mining revenue with its 365-day average; a reading above 1 indicates that revenue from newly issued BTC is above that average. It does not account for miners’ electricity, hardware, or financing costs.
Key price levels to watch
Since retreating from a September high near $87,374, Bitcoin has mostly traded between $83,000 and $85,000. Resistance is clustered between $85,500 and $86,000. A break above that zone could put the earlier high back in play. If BTC falls below $83,000, traders may watch the $80,000–$81,000 area for support.
Derivatives activity has cooled during the pause. Open interest dropped 6.5%, and 24-hour Bitcoin liquidations fell 88% to $7.45 million, pointing to fewer leveraged positions and fewer forced closures.
Inflation data looms
The next U.S. inflation reading is scheduled for Sept. 30, when the Bureau of Economic Analysis releases its August personal income and outlays report. The data will include the personal consumption expenditures price index, a gauge closely watched for its impact on interest-rate expectations.
Some traders refer to October as "Uptober" because Bitcoin has often gained during the month, but past performance does not guarantee a repeat. Near term, BTC’s response will depend on the inflation data and whether the price can hold its nearby support levels.
