• Billionaires were getting $10 billion richer every day in January. Just one month later, Elon Musk, Jeff Bezos, Larry Ellison, and Mark Zuckerberg have lost a combined total of $138 billion.  

This January felt like the honeymoon period for billionaires, who saw their wealth surge by $10 billion every day. One month later, the daydream is over, and their net worth is tanking.
