Bitcoin made a strong start to 2025 and increased market domination. Intensive institutional demand for Spot Bitcoin ETFs and political developments in the United States further increase the weight of BTC in the crypto market. However, Ethereum and other Altcoins continue to lose value against Bitcoin.
Bitcoin dominance is increasing
The BTC Dominance Index (BTC.D), which measures Bitcoin’s dominance against the total crypto currency market value, increased by 15.4 %in January to 59 %. In the last three years, Bitcoin’s market domination has increased by 58 %.

Coinbase CEO Brian Armstrong, every week in the USA that approximately 1 million new token was createdstated that this situation affects the market structure. However, despite the expansion in the Altcoin market, Bitcoin’s market share continues to grow.
Can ETF flows BTC for $ 200,000?
The interest of corporate investors is one of the biggest factors supporting the rise of the BTC. The total assets of Spot Bitcoin ETFs reached 39,57 billion dollars and doubled a level of $ 1.17 billion a year ago.

In addition, Bitcoin whales accumulate a large amount of BTC. In particular, Microstrategy and some large funds increase the procurement pressure in the market by increasing BTC assets. In fact, some analysts predict that Bitcoin can reach $ 200,000 at the end of 2025 if ETF entrances continue.
US politics paves the way for Bitcoin
US President Donald Trump and some senators strengthen the position of BTC with pro -Bitcoin statements. Wyoming, Arizona and New Hampshire, states, Bitcoin plans to evaluate as a strategic asset.

With Trump’s decree on January 23, the idea of creating a national BTC reserve came to the agenda. These developments are seen as important steps to strengthen Bitcoin’s digital gold status by receiving more government support.
Altcoin season is the past now?
Market analysts say Bitcoin is separated from Altcoins. Historically, BTC and Altcoins act together, but the latest data show that BTC has entered a trend of ascension independent of the rest of the market.

River Financial Manager Sam Wouters, “There is no lower season anymore”He said that investors should accept that BTC stands out in this cycle.
Ethereum loses power against Bitcoin
Ethereum’s depreciation against Bitcoin continues. ETH/BTC parity has fallen by 65 %since 2022, which was recorded as one of the longest decline trends in the history of Ethereum.
Although US -based Spot Ethereum ETFs have recorded entry since November, Bitcoin funds have been 90 %of the total entrances in the sector since the beginning of the year. In addition, Ethereum’s high trading fees and slow approval times cause investor interest to shift to rival platforms such as Solana.

According to technical analysis, ETH/BTC parity can test the 0.030 BTC level. If this support is not preserved, it is possible for Ethereum to decrease to 0.023 BTC. On the contrary, if a recovery occurs, a movement can be expected towards 0.040 BTC level.

On the basis of US dollar, the level of $ 3,500 for Ethereum stands out as an important resistance point. Exceeding this level can support the recovery of ETH.
Conclusion: Bitcoin stands out, Altcoins are at risk
Bitcoin’s rising domination and corporate interest in ETFs make BTC leader in the market in 2025. While the expectations of the Altcoin season weaken, large projects such as Ethereum continue to lose value against Bitcoin. Investors should closely follow Bitcoin’s market movements as a decisive factor in the coming period.
