Ripple's former CTO David Schwartz recalled that he sold 40,000 ETH at $1.05 per coin, making a profit of $42,000, achieving a 321% return compared to his initial purchase price of $0.311. He used this money to buy solar panels for a property he no longer owns. Schwartz holds BTC, ETH, and other cryptocurrencies, and he chose to hold a 2% stake in Ripple rather than XRP. It is estimated that his net worth is between $90 million and $500 million.
