Kevin O'Leary said Bitcoin can reach $1 million only if the industry addresses the risk that quantum computers could eventually compromise the cryptography securing the network, a scenario known as Q-Day. He said unresolved security concerns discourage institutions from treating Bitcoin as a core holding, while some investors are hedging the risk through emerging quantum-computing companies. Speaking on The Rollup podcast during Avalanche Summit in New York, O'Leary said his earlier thesis that Bitcoin and Ethereum would capture 97% of crypto-market volatility and that Ethereum would become the dominant standard had failed to materialize. He now expects individual industries to adopt different blockchains, with the network chosen by the first major exchange to tokenize assets potentially becoming essential infrastructure. The Securities and Exchange Commission has issued an Innovation Exemption allowing approved platforms to trade tokenized stocks. O'Leary said crypto has represented as much as 23% of his portfolio over seven years, despite limits of 5% in a single stock and 20% in a single sector. Outside crypto, he is investing in power infrastructure, uranium and small modular reactor-related opportunities to meet rising AI data-center demand, including BitZero and projects in Norway, Finland, Alberta and Utah.
