Bitcoin began the new month facing resistance above $85,000 as the largest cryptocurrency by market capitalization moved through its usual back-and-forth trading. A rise toward $85,000 followed Wednesday’s better-than-expected personal consumption expenditures (PCE) data, a closely watched inflation measure. The move came hours after bitcoin ended September with a net gain, securing its second consecutive positive month. The uncommon two-month winning streak has shifted attention toward Uptober, the historically bullish October pattern for digital assets. PlanB, a prominent pseudonymous quantitative analyst, said bitcoin remains "extremely undervalued."
