币界网报道：Cryptocurrency-related stocks surged as Bitcoin (BTC) climbed above $50,000 for the first time since December 2021, fueling optimism in the broader digital asset market. Companies like Coinbase (COIN), MicroStrategy (MSTR), and Marathon Digital (MARA) saw significant gains, with Coinbase shares rising over 10% in pre-market trading. The rally follows growing institutional interest, including BlackRock’s spot Bitcoin ETF reaching $10 billion in assets under management in just seven weeks. However, analysts remain cautious about an imminent "altcoin season," as Bitcoin dominance holds steady near 52%, suggesting capital hasn’t broadly shifted to smaller-cap tokens yet. Some altcoins, like Ethereum (ETH), Solana (SOL), and Avalanche (AVAX), posted modest gains but lagged behind Bitcoin’s momentum. Market observers note that while retail interest is picking up, institutional flows continue to favor Bitcoin, delaying a potential altcoin surge. Meanwhile, crypto miners benefited from Bitcoin’s price rise, with Riot Platforms (RIOT) and CleanSpark (CLSK) also seeing double-digit stock increases. The overall crypto market cap surpassed $2 trillion, signaling renewed bullish sentiment, though traders warn of potential volatility ahead as macroeconomic uncertainties persist.
