Canadian investor Kevin O'Leary, famed for his role on 'Shark Tank,' has streamlined his cryptocurrency portfolio to focus exclusively on Bitcoin (BTC) and Ethereum (ETH). O'Leary believes these two cryptocurrencies capture over 90% of the market's alpha and volatility, rendering other tokens unnecessary. He emphasizes the rising significance of stablecoins, particularly with a new stablecoin bill in the US, and anticipates Ethereum will benefit from this development. O'Leary also regards Bitcoin as a store of value, forecasting its price could soar to $250,000. He has allocated more than 10% of his net worth to BTC and related assets.
