Bitcoin continues to struggle during one of its historically strongest months, often referred to as “Uptober,” currently down more than 5% and trading below $108,000, as it approaches several critical support and resistance levels.
The 200-day Simple Moving Average (200SMA), a key indicator that often separates bull and bear markets, now sits at $107,846 and acts as immediate resistance.
Since the 2023 cycle began, bitcoin has mostly held this level as support, but it slipped below it in the summers of 2023 and 2024 and again in April 2025. The 365-day SMA, which provides a broader view of long-term momentum and sits at $100,367, has consistently served as a secondary support when the 200DMA fails. This is the fourth time in this cycle that bitcoin’s price has been sandwiched between these two averages, a range-bound setup that can last for months.
Additional key levels include $103,509, the average cost basis of 2025 investors according to Checkonchain data. This serves as an important price floor, as well as the $100,000 psychological support level that anchors market sentiment.
On the upside, $112,100 represents the short-term cost basis, which reflects the average onchain acquisition price for coins moved within the past six months.
Historically, bitcoin has dipped below this level during corrections, but sustained trading above it typically signals the resumption of a bull market.
