- Bitcoin's market dominance fell to 61% as altcoins like Ethereum and XRP surged over 20% in a week.

- Analysts note altcoin momentum requires Bitcoin dominance reversal, but U.S. spot ETFs limit asset rotation.

- Meme coins (Bonk, Floki) and Altcoin Season Index (43) suggest potential "altcoin season," though trends remain unconfirmed.

- Federal Reserve rate cuts and crypto legislation could drive liquidity, but sustained altcoin growth needs major macro events.

Bitcoin's dominance in the cryptocurrency market has been gradually decreasing, although it is still too early to determine if this trend will continue. Adrian Fritz, head of research at a Switzerland-based asset manager, noted that while the prices of many altcoins are surging, a sustained period of momentum for altcoins would require a trend reversal in Bitcoin's dominance.

As of Friday, Bitcoin's dominance stood at around 61%, with a market capitalization of $2.3 trillion. This represents a slight decrease from its peak of 65.5% last month, which was recorded across 17,000 cryptocurrencies tracked by a crypto data provider. The drop in Bitcoin's dominance coincides with significant gains in Ethereum and XRP, which have increased by 20% to $3,600 and 23% to $3.46, respectively, over the past week. XRP, in particular, hit a record high during this period. Additionally, meme coins such as the Solana-based Bonk and Ethereum-based Floki have surged by over 45% each.

Historically, altcoins have shown strength after Bitcoin's price peaked, as traders rotate toward more volatile assets seeking higher returns. However, the crypto market has evolved significantly in recent years, including the debut of spot Bitcoin exchange-traded funds in the U.S. This product does not allow investors to reach for another asset on-chain, making it difficult to imagine Bitcoin's dominance dropping to levels seen in previous bull markets. Over the last year, the spotlight has definitely been on Bitcoin.

Interest rate cuts from the Federal Reserve, if they occur later this year, could be a major catalyst for an altcoin season by injecting liquidity into the market. Until a significant macro event occurs, the market may experience a bit of euphoria. The sentiment was echoed by the CIO of a venture capital firm, who noted early signals of an 'altcoin season' but stated it is not fully underway yet. With momentum for crypto legislation on Capitol Hill, some investors are likely racing to price in regulatory tailwinds for the digital assets sector.

There are some indications that altcoin season may be approaching, such as the Altcoin Season Index, which looks at the performance of the top 100 cryptocurrencies by market cap over the past 90 days. On Thursday, the index hit 47 before falling to 43 on Friday. A value of 100 indicates that altcoin season is in full swing. However, it is still too early to tell if this trend will continue, and more data is needed to make a definitive conclusion.
