Bitcoin briefly loses 2025 gains as crypto plunges over the weekend.

• Bitcoin's recent decline has erased its gains for 2025, dropping below its annual starting price of $93,507 amid a significant market downturn over the weekend.

• Despite positive industry developments, factors like the US government shutdown and profit-taking by long-term investors have pressured Bitcoin prices.

• Analysts speculate on the continued relevance of the four-year cycle theory and anticipate a possible Bitcoin resurgence in 2026 due to strong market fundamentals.

Bitcoin experienced a sharp decline this weekend, briefly erasing its 2025 gains and dipping below its year-opening value of $93,507. The cryptocurrency fell to a low of $93,029 on Sunday, representing a 25% drop from its all-time high in October. Although it has rebounded slightly to around $94,209, the pressures on the market remain significant.

The downturn occurred despite the reopening of the U.S. government on Thursday, which many had hoped would provide essential support for crypto markets. This year initially appeared promising for cryptocurrencies, particularly after the inauguration of President Donald Trump, who has established the most pro-crypto administration thus far. However, ongoing political tensions—including Trump's tariff strategies and the recent government shutdown, lasting a historic 43 days—have contributed to several rapid price pullbacks for Bitcoin throughout the year.

Market dynamics are also being influenced by Bitcoin whales—investors holding large amounts of Bitcoin—who have been offloading portions of their assets, consequently stalling price rallies even as positive regulatory developments emerge. Despite these sell-offs, analysts from Glassnode argue that this behavior aligns with typical patterns seen among long-term investors during the concluding stages of bull markets, suggesting it is not indicative of a mass exodus.

Notably, Bitcoin is not alone in its struggles, as Ethereum and Solana have also recorded declines of 7.95% and 28.3%, respectively, since the start of the year, while numerous altcoins have faced even steeper losses.

Looking ahead, questions linger regarding the viability of the four-year cycle thesis, particularly given the increasing institutional support and regulatory frameworks now in place in the crypto landscape. Matt Hougan, chief investment officer at Bitwise, remains optimistic, suggesting a potential Bitcoin resurgence in 2026 driven by the “debasement trade” thesis and a broader trend toward increased adoption of stablecoins, tokenization, and decentralized finance. Hougan emphasized the soundness of the underlying fundamentals, pointing to a positive outlook for the sector in the longer term.
