a cab driver turned $1,000 into $2 million (Ad)

A cab driver once turned a $1,000 investment into more than $2 million by spotting an early automation trend before Wall Street caught on. Now a new wave of machine labor begins in November, when the first machine workers clock in for paid shifts. Dylan Jovine of Behind the Markets believes the company behind this shift could turn a $10,000 investment into $74,000 over the next decade.tc pixel
