Altcoin season could return, according to Crypto news, as Ethereum has gained nearly 30% in the last week, while Bitcoin added only 5%. According to TradingView data, ETH even reached a high of $4,792, close to its all-time high from 2021.

Altcoin season may be on the horizon

On-chain analytics company Glassnode points out that Ethereum is again acting as a “market barometer” and could set the pace for other cryptocurrencies. Over the past six days, $2.3 billion flowed into spot ETFs focused on Ethereum, including a record $1 billion in a single day, according to Farside data. Since the beginning of July, ETH ETFs have attracted $1.5 billion more capital than Bitcoin ETFs.

Ethereum’s strong position is also confirmed by on-chain data from DefiLlama. The total value locked in DeFi reaches approximately $96 billion, which is more than 60% of the entire market.

Bids for #Ethereum continue to strengthen with the asset marching toward ATHs, while #Bitcoin consolidates just below its peak.

Falling Bitcoin dominance

Bitcoin dominance has dropped from a cyclical high of nearly 66% in June to the current 59.44%, falling below 60% for the first time in half a year. This decline ended a more than 1,020-day period of increasing Bitcoin dominance and signals a shift of investor interest toward altcoins.

Altcoin season index from Blockchain Center remains at 55, which is in the neutral zone. To confirm an altcoin season, at least 75% of the top 50 altcoins must outperform Bitcoin over the last 90 days. The average length of an altcoin season is 18 days, but the longest period without one was 117 days, and the current 240 days is therefore among the longest.

Historically, altcoin seasons are accompanied by strong growth in projects like Solana, Cardano, and Ethereum, increased altcoin trading volumes, and a higher share in ETF inflows. We can currently observe exactly this trend, and we just need to wait for the profits from highly capitalized coins to flow into smaller ones. This period is when the peak of the cycle is likely to form.

Capital flow logic

Currently, market gains have flowed into highly capitalized coins like XRP, Ethereum, or Binance Coin, which are breaking records. The next phase is the transfer of capital to smaller altcoins and shitcoins. This process usually takes about two weeks and ends with the peak of the entire market cycle.

If the trend of falling Bitcoin dominance deepens and capital spreads across the broader market, altcoin season may be closer than it seems, although confirmation has not yet arrived.
