The Altcoin season could be on the horizon while the momentum passes through the cryptography market. Bitcoin domination has increased from more than 65% to 63.89%, just as BTC exceeded $ 100,000 for the first time since February 3.
This sparked a large rally of Altcoin, with Ethereum by almost 13% and major names like soil, Doge and Ada each win more than 6%. Combined with a rebound in the ETH / BTC ratio from its lowest levels since 2020, the configuration suggests a possible rotation in altcoins for the first time in months.
Altcoin incoming season? The domination of the bitcoin plunges that eth and majors increase
Bitcoin domination has dropped more than 65% to 63.89% in just a few hours after BTC exceeded $ 100,000 for the first time since February 3.
This change triggered a solid Altcoin rally, Ethereum jumping almost 13% in the last 24 hours, while Solana (soil), Dogecoin (Doge) and Cardano (ADA) each earned more than 6%.

Until yesterday, the domination of Bitcoin has been at its highest level since January 2021, showing how large BTC has outperformed the larger market in recent months.
A sudden reversal like this often signals a rotation of capital, traders starting to move the benefits of the BTC to altcoins. Recently, the CEO of cryptochus Ki Young Ju called Bitcoin Cycle Theory Obsolete while Tradfi takes over.
Adding to this story is the ETH / BTC ratio, which has recently reached its lowest level since 2020 – marking an Ethereum sub -performance extended compared to bitcoin.

A rebound in these historic stockings could indicate the start of a structural change promoting altcoins. If the domination of the BTC continues to fall while ETH / BTC increases, it would be a strong signal that the market passes to an Altcoin season.
The Altcoin volumes increasing and the capital turning in wider sectors, May 2025 could start a great season of Altcoin.
May 2025: a turning point to the Altcoin season?
The CoinmarketCap Altcoin season index increased from 23 to 36 in the last four days. This index follows if Bitcoin or Altcoins surpass a specific period.
The readings less than 25 indicate the “bitcoin season”, where BTC exceeds most altcoins. The scores between 25 and 75 are considered neutral, while the values greater than 75 officially signal the “Altcoin season”.

The current jump in neutral territory occurs after reaching an annual hollow of 12 at the end of April – his weakest point since December, when he culminated at 87.
The CMC Altcoin season index measures if at least 75% of the 100 best parts (excluding stablescoins and tokens supported by assets like WBTC and Steth) have surpassed Bitcoin in the last 90 days.

Until now, in 2025, Bitcoin has increased by 10% up to date, which has performed almost all the main altcoins except XRP, which earned more than 12%. Meanwhile, Ethereum remains down 30% YTD, and parts like Link, Doge, Avx and Shib have all dropped by more than 20%.
Despite this low performance YTD, the clear drop in the domination of the BTC, strong Altcoin rallies in early May, and the Altcoin growing index indicates the possibility that May 2025 can start a new season of Altcoin.
