Apart from Bitcoin (BTC), altcoins such as Ethereum, XRP and Solana also began to attract attention within the scope of the treasury strategy. At this point, while many companies have added altcoins such as ETH and XRP to their reserves, the latest move came from Thumzup, where US President Donald Trump's son, Donald Trump Jr., is also a shareholder. The company announced in its official statement that it will expand its Bitcoin-focused treasury strategy to include Ethereum (ETH), Dogecoin (DOGE), Litecoin (LTC), Solana (SOL), XRP, and USDC. 6 More Altcoins to Buy Besides Bitcoin! Thumzup Media Corporation, a Nasdaq-listed brand and social media marketing solutions provider, announced that its Board of Directors has approved an expanded list of digital assets for its crypto treasury strategy. The company's board has expanded its previous strategy, which paved the way for holding up to 90% of its liquid assets in Bitcoin. Accordingly, in addition to Bitcoin (BTC), the company will now be able to hold DOGE, LTC, SOL, XRP, ETH and USD Coin (USDC) in its reserves. Thumzup also disclosed that President Donald Trump's son, Donald Trump Jr., owns 350,000 shares in the company, worth approximately $4 million at current prices. Trump Jr.'s stake in Thumzup is the latest move by the Trump family to invest in companies pursuing cryptocurrency treasury strategies.
