Bitcoin's dominance fell from 55.4% to less than 50% following US President Donald Trump's announcement that XRP, Solana and Cardano would be included in the country's "Crypto Strategic Reserve."
Trump later confirmed on Truth Social that Bitcoin and Ether would be "at the heart of the reserve," but the inclusion of altcoins disappointed some Bitcoin enthusiasts and even a Bitcoin critic.
The dominance of Bitcoin has now fallen to 49.6%.
During the same period, Solana and Ether also rose 25.5% and 13.1%, respectively, while other altcoins not explicitly mentioned in Trump's announcement also saw gains.
Meanwhile, Bitcoin only rose 10% to $94,200.
The Trump administration's decision to avoid establishing an exclusive reserve for Bitcoin caught some by surprise, including Bitcoin critic Peter Schiff, who questioned the rationale for including altcoins.
