Billionaire investor Kevin O'Leary, known for his straightforward financial advice, has made a bold prediction about the future of cryptocurrency. According to Watcher.Guru, O'Leary believes that the vast majority of altcoins are destined to fail, labeling them as "shitcoins" with no long-term viability. O'Leary's analysis points to Bitcoin (BTC) and Ethereum (ETH) as the only cryptocurrencies likely to survive the impending market shakeout. He argues that their established networks, developer activity, and institutional adoption provide a solid foundation that most altcoins lack. While the altcoin market has seen periods of rapid growth and innovation, O'Leary's perspective highlights the inherent risk and volatility associated with investing in less established cryptocurrencies. His words serve as a reminder of the importance of due diligence and careful consideration when navigating the complex world of digital assets. ```
