Jordan Belfort, known as The Wolf of Wall Street, shared his views on cryptocurrency, retail investing, and his upcoming book in an interview with Benzinga. Belfort, who once called cryptocurrency a scam, now acknowledges Bitcoin and Ethereum as legitimate, but still believes the sector needs regulation. He also mentioned that retail traders today have better tools and access to more information. His new book, 'The Wolf of Investing,' due in October, will cover advice and tools for investors, emphasizing that the bulk of one's investment should be in an S&P 500 index fund.
