Kevin O’Leary, known as "Mr. Wonderful," questioned whether Ethereum will become the standard network across all 11 sectors of the S&P 500, citing concerns about its transaction speed. He pointed to Solana and Avalanche as networks that could attract industry adoption and hinted at placing investments across multiple chains. Chainspect data showed Solana processing more than 1,262 transactions per second, compared with 22.44 for Ethereum and 10.40 for Avalanche. O’Leary also highlighted Avalanche subnets, which operate with customized rules and independent validator sets while connecting to the wider Avalanche ecosystem. His comments marked a shift from his earlier view that Bitcoin and Ethereum alone could capture 97.5% of cryptocurrency-market volatility and yield. At the time of writing, ETH traded at $2,698.08, up 4.90% over 24 hours; AVAX rose 15.60% to $11.16, while SOL jumped 7.1% to $116.05, according to Benzinga Pro.
