traders expect Bitcoin to possibly rebound in the short term. Data shows that the Relative Strength Index (RSI) of BTC/USD is in an extremely oversold state, with the indicator dropping to its lowest level in nearly three years. Bitcoin has fallen 36% from its all-time high of $126,000 to $80,500, which has had a significant impact on the RSI indicator on higher timeframes. On the weekly chart, the RSI has dropped from a local high of 64 in September to the current 35, a level last seen in January 2023, when Bitcoin was trading around $15,500-$17,000.

Analyst Jelle stated: Historically, when the weekly RSI reaches this level, it is worth paying attention.

He added: Either we are close to the bottom, or we will soon experience a larger downturn. Mister Crypto pointed out in an X post on Friday that Bitcoin's Stochastic Relative Strength Index (Stochastic RSI) shows its oversold degree is the deepest in the entire cycle, making a short-term rebound very likely.

according to Coinglass data, the Coinbase Bitcoin premium index has been in negative premium for 5 consecutive days, currently at -0.065%.

The Coinbase Bitcoin premium index is used to measure the difference between the Bitcoin price on Coinbase (a mainstream US trading platform) and the global market average price. This index is an important indicator to observe capital flows in the US market, institutional investment enthusiasm, and changes in market sentiment. A positive premium indicates that the Coinbase price is higher than the global average, usually meaning: strong buying in the US market, active participation of institutions or compliant funds, abundant dollar liquidity, and optimistic investment sentiment. A negative premium indicates that the Coinbase price is lower than the global average, usually reflecting: significant selling pressure in the US market, a decline in investors' risk appetite, rising market risk aversion sentiment, or capital outflow.

On December 19, Web3 smart advertising platform Ads3 announced the completion of a new round of strategic financing from Animoca Brands. This round of financing will strongly drive Ads3's global market expansion and empower the innovation and scalable development of the decentralized advertising ecosystem.

Previously, Ads3 had received support from many well-known industry institutions such as Web3 Labs, AB Foundation, and Footprint Analytics. The completion of this round of financing further reflects the strong recognition from leading capital for Ads3's vision to connect the value systems of Web2 and Web3 and to reconstruct advertising infrastructure.

This infrastructure-level layout enables Web2 users to seamlessly enter the Web3 ecosystem, while also helping advertisers maximize their advertising ROI under the premise of compliance and efficiency through effect-oriented data-driven billing models such as OCPC and OCPM.

Tom Lee, chairman of Ethereum treasury company BitMine, said in an interview with CNBC, "I believe Bitcoin has not yet peaked. We were too optimistic about achieving this goal before December. But I do believe Bitcoin can reach a new all-time high before the end of January 2026. So, we should not assume that the prices of Bitcoin, Ethereum, or cryptocurrencies have already peaked."

according to Onchain Lens monitoring, a certain whale is shorting 1125.2 BTC with 40x leverage. The current position is valued at 99 million USD, with a liquidation price of 89,130.95 USD. In previous trades, the whale has already lost over 3 million USD.

 Jurien Timmer, Global Macro Director at Fidelity, posted on platform X that although he remains long-term bullish on Bitcoin, Bitcoin may have already ended another four-year halving cycle, both in terms of price and time: after 145 months of rising, the $125,000 peak reached in October this year basically meets expectations. Bitcoin's winter usually lasts about a year, so 2026 may be Bitcoin's "resting year," with support levels between $65,000 and $75,000.

In addition, Jurien Timmer also emphasized the strong performance of gold in 2025 and contrasted it with Bitcoin's negative performance, expecting that neither of these two assets will experience mean reversion in the short term. He pointed out that gold is currently in a strong bull market, having risen about 65% year-to-date, outperforming the growth of global money supply. During the recent pullback, gold held most of its gains, which is a typical characteristic of a bull market.
