Kevin O'Leary, during a discussion at Benzinga's Crypto Unlocked event, emphasized the need for institutional investment in cryptocurrencies like Bitcoin (BTC) for their value to increase. He stated that the 'Wild West' era of crypto, characterized by lack of regulation and high speculative trading, needs to end for a more stable financial ecosystem to emerge. O'Leary also highlighted the need for a regulatory framework that mitigates risks associated with fraudulent activities in the crypto space.
