According to the latest report, the wealthiest person in the world is Jeff Bezos. He is the founder of Amazon, a global e-commerce company.
International Business Times: World's richest man Jeff Bezos earned more than the combined GDP of 28 countries last year
Amazon was developed in 1994 as Cadabra.com. It was originally a book delivering service. As it broadened the range of business gradually, we can purchase almost everything, from vegetable to furniture at Amazon.com. In Japan, you can order even a funeral ceremony with a Buddhist priest through Amazon.co.jp.
Bezos is counted as a modern giant as well as Steve Jobs, Bill Gates, and Mark Zuckerberg. They won great success in addressing the internet era. They have changed the world to the better direction. I truly respect them.
On the other hand, there are some people who have earned much money with cryptocurrency recently. Chris Larsen, co-founder of Ripple, was named as the world eighth richest person. He is considered to possess approximately five billions of Ripple, equal to 15 billion USD. With stocks calculated, his property reaches 50 billion USD.
Cryptocurrency is one of the most innovations in these some decades. It is not surprising that those have committed it earn much money.
However, it seems a little strange that their property is calculated using the conventional money. In the future, the measure of income itself will become nonsense as a value-calculator, I prospect.
