Kain Warwick, founder of Synthetix and Infinex, has paid $50,000 to Multicoin co-founder Kyle Samani after losing a bet on Ethereum's price. The wager, made in November 2024, hinged on whether ETH would surpass $25,000 by the end of 2025. Warwick's loss resulted in the $50,000 payout, while a win would have seen Samani pay $500,000.
