Large-Cap Altcoins Surge as Crypto Market Enters Altseason

Major altcoins are surging, Crypto Rover (@rovercrc) announced that it is the beginning of Phase 4: Altseason. Coins such as Binance Coin (BNB), Solana (SOL), and Cardano (ADA) are at the forefront. BNB is trading around $490, Solana trading at 95 and Cardano at 1.20 with year to date returns of 70-100%. On big platform exchanges such as Binance, large caps are trading up to $20 billion every day. According to market analysts, the interest of investors in large caps has increased since the spot ETF of Ethereum was approved in the U.S. in July 2025.

Large caps are starting to rip.

What's next is obvious.

In January 2025, Altcoins took up 40 percent of the world crypto trading volume, compared to 25 percent in January 2025. The institutional investors plan big inflows. MicroStrategy owns 10 billion Bitcoins. BlackRock ETFs are worth $20 billion in crypto. This institutional action helps to prop up altcoin pumps.

Bitcoin ETFs

In the UK, the financial conduct authority (FCA) is to remove its crypto ETFs prohibition this week ( October 612, 2025 ). High volatility and risk of fraud warranted the initial ban which began in January 2021. As justification, the FCA mentioned 30% average monthly price swings in crypto and $2 billion lost to scams in 2020.

The change is an extension of the Financial Services and Markets Act 2023, which regulates cryptoassets and stablecoins. The London Stock Exchange will examine ETF prospectuses, probably making them accessible to retail by October 20, 2025. Researchers predict that the UK has a crypto market worth $300 million that may increase with inflows of between 5-10 billion due to the introduction of retail ETFs.

International precedent is very influential. In January 2024, the approvals of U.S. Bitcoin ETFs caused a 15 percent price rise in less than a week and inflows of $15 billion in half a year. In 2024, Hong Kong and Australia issued crypto ETFs, including raising $2 billion in aggregate, compelling the UK to take action.

Bitcoin and Ethereum Precondition

Bitcoin is trading at $123,120 having a market cap of 2.53 trillion dollars and 20.5 million Bitcoins in circulation. Bitcoin rose 45% year-to-date. The market value of Ethereum hit 450 billion with an annual growth of 60 percent. The ratio of Ethereum increased to 18% in the last quarter, initiating a transition in gains led by Bitcoin to those made by altcoins.

The history reveals that Bitcoin dominance of less than 50% is a signal of Altseason. By November 2025, analysts project that Bitcoin dominance will be in the 45-48 per cent range. Other coins often pump later, with less-capitalized coins such as Arbitrum (15B) and less-capitalized coins such as Fantom (2B) increasing 3x to 5x during previous cycles.

Altseason Dynamics

Phase 4 Altseason displays any coins that are pumping with a strong fundamental. Move on large caps first. Mid caps and low caps come in weeks later. The flipping story starts anew with Ethereum potentially overtaking the market cap of Bitcoin in 2026.

Trading volumes remain high. By October 2025, global crypto volume reaches to $150 billion per day. According to on-chain data, in the last 24 hours, there are 200 million in BTC and altcoin transfers. The Crypto Fear and Greed Index stands at 75 (Greed) indicating market mania.

Volatility is an issue. The average 30-day volatility of bitcoin in 2025 is 28%. Regulatory delays may occur. Retail caps, such as those of £10,000 to £20,000 per investor, could be introduced by the FCA. There are risks of market manipulation. Previous altseasons included pump-and-dump schemes such as SafeMoon in 2021. Altcoins are associated with Bitcoin; a 20 percent decrease in BTC would terminate Altseason.
