- They are smart investors
According to a new report from the research firm Wealth-X, 60% billionaires made their money without a massive inheritance. Of these, 19.3% of them made their fortune in finance & banking. In other words, they are smart investors that perform a lot of research before making an investment. Many have historically invest in what they know. Not everyone is a Warren Buffet that can master the public stock market, but perhaps the knowledge of your industry may be applied to external investment opportunities.
