Bitcoin's recent surge to an all-time high of $100,000 is igniting hopes for a sustained altcoin season, with analysts predicting a 'Santa Rally' for cryptocurrencies like XRP and Solana. Key drivers include Donald Trump's election victory, which is expected to ease regulatory pressures, and increased institutional adoption, particularly with the anticipated launch of more crypto ETFs. As Bitcoin's market dominance declines to under 54%, traders are increasingly shifting their focus to smaller altcoins.
