Top Altcoins Set for Big Moves in December 2025
Looking at Bitcoin's price performance this year, the coin's price has only increased about 13% year-on-year, from about $94,000 to $107,000.
According to Altcoin Daily , data from 2013 to 2024 shows that if investors miss out on Bitcoin's most productive days, average annual returns will turn negative.
As Fundstrat's Tom Lee explains, Bitcoin's biggest rallies have typically come in short bursts, often in the last quarter of the year. He believes a similar scenario is shaping up again, driven by a number of factors.
The US Federal Reserve is expected to start easing interest rates, while the government shutdown has prompted investors to move into riskier assets. In addition, easing tensions between the US and China could continue to boost market sentiment.
Seasonal trends also favor a broader stock market recovery, which has historically benefited Bitcoin. Lee believes Bitcoin could surge before the end of the year, potentially even hitting $200,000 if the last 10 “magic days” occur again.
The market structure bill could be a turning point
Another important reason for optimism comes from Washington. Coinbase CEO Brian Armstrong recently revealed that, despite the government shutdown, the US Senate has completed about 90% of the long-awaited Cryptocurrency Market Structure (Transparency Act) bill, one of the most important crypto-related pieces of legislation to date.
Armstrong said there is a broad consensus among Democrats and Republicans, with only minor disagreements remaining on DeFi regulation and stablecoin rewards. The bill could pass the committee before Thanksgiving, providing long-term clarity for crypto companies and investors.
He also stressed the importance of resisting pressure from major banks that want to restrict the use of stablecoins, noting that the bill aims to “protect innovation” while ensuring proper regulation of centralized exchanges, not decentralized protocols.
Altcoins are ready to ride the wave
If Bitcoin rallies, analysts predict major altcoins will follow suit. Ethereum is seeing record stablecoin growth, Solana recently launched trading through Fidelity's brokerage platform, and BitTensor (TAO) is preparing for its first halving event in December, a move that will cut supply, similar to Bitcoin's model.
With just a few weeks left until 2025, investors are watching closely. If Bitcoin’s “best 10 days” pattern continues to hold, the biggest gains of the year could still be ahead, and missing them could mean missing out on the market’s biggest bull run, according to analysts at Altcoin Daily.
