Bitcoin News Today: Altcoin Rally Gains Momentum as XRP SOL DOGE Surge 45% 30% 46% Amid Bitcoin's Declining Dominance

The altcoin market is poised for a significant rally in the second half of 2025, with Ripple (XRP), Solana (SOL), and Dogecoin (DOGE) emerging as standout performers amid a waning Bitcoin dominance. Bitcoin’s market share hit a five-month low of 60.51% on July 21, 2025, marking a critical inflection point for alternative cryptocurrencies [1]. Analysts note that a sustained Bitcoin dominance below 62% historically signals the onset of an altcoin season, where non-Bitcoin assets outperform the leading cryptocurrency [1]. This trend is already materializing, with XRP, SOL, and DOGE posting double-digit gains over the past month—45%, 30%, and 46%, respectively—while Bitcoin’s price stagnates near $118,000 [1].

Ripple’s XRP has gained traction despite rising selling pressure, trading at $3.1755 as of mid-July 2025, or 14% below its all-time high. Exchange volume for XRP surged 6% in the past month, reflecting growing demand from retail and institutional investors [1]. Solana’s ecosystem has also seen robust growth, with total value locked (TVL) increasing by $2.4 billion over four months and decentralized exchange (DEX) volume exceeding $3.5 billion in 24 hours. SOL’s price rose 30% in a month, reaching $186, with technical analysis suggesting potential for a test of $220 resistance [1]. Dogecoin, meanwhile, has maintained strength above key support levels, surging 45% in a month to $0.2378. Its price correlation with Bitcoin (0.84) and stable derivatives activity indicate resilience amid broader market corrections [1].

Institutional adoption and capital flows are amplifying the altcoin rally. Tesseract’s CEO James Harris highlighted that corporations are increasingly treating crypto as a treasury asset, with entities like Strategy (formerly MicroStrategy) and Sharplink Gaming accumulating Ethereum and Solana [1]. Kraken’s Alexia Theodorou emphasized Dogecoin’s role as a high-beta asset, with July’s perpetual futures volume doubling previous records and funding rates hitting annual highs [1]. These dynamics underscore a broader capital rotation from Bitcoin to altcoins, driven by profit-taking in BTC and renewed speculative demand for growth-oriented tokens [1].

However, volatility remains a factor. XRP faces elevated selling pressure on exchanges, while SOL could retest $120 support in the short term. Dogecoin’s open interest decline and a long/short ratio of 0.91 on Coinglass suggest cautious positioning among traders [1]. Despite these risks, experts argue that the current altcoin season is distinct from prior cycles due to institutional participation and blockchain innovation. For example, Solana’s TVL growth and Ethereum’s integration with Bitcoin DeFi projects signal a shift toward interconnected ecosystems [1].

The market’s trajectory hinges on Bitcoin’s stability. While BTC dominance has recovered slightly, it remains below 62%, creating favorable conditions for altcoins to continue outperforming [1]. If Bitcoin sustains its recent support levels, the altcoin rally could extend into late 2025, with blue-chip tokens like XRP, SOL, and DOGE leading the charge.
