Kevin O’Leary, known as Mr. Wonderful from Shark Tank, advises new investors to focus on Bitcoin and Ethereum, citing their dominance and stability in the volatile crypto market. In a recent interview on FOX Business, O’Leary revealed he has exited altcoin investments, labeling them "pooh-pooh coins" due to their high failure rate and volatility. O’Leary emphasized the safety and exposure provided by Bitcoin and Ethereum, which he believes cover 97% of the volatility of other cryptocurrencies. He highlighted the growing institutional adoption of blockchain technology as a supporting factor for his investment strategy. Despite the risks, O’Leary maintains that Bitcoin and Ethereum are the best options for investors seeking reliable high-tech assets.
