How the World's Richest Have Sized Things Up

We take a look at four of the five richest people in the world and their take on Bitcoin and cryptocurrencies in general.

It's almost impossible to find any comments made by Bezos directly talking about Bitcoin, cryptocurrency or blockchain technology.

The Foundation has supported projects like Bitsoko in Ghana, which has pioneered a Bitcoin merchant payment processing and Bitcoin wallet service in Ghana and other African countries.

Gates' latest take on Bitcoin was in an interview on CNBC's Squawk Box, where he said that he "Would short it if there was an easy way to do it".

"Bitcoin is exciting because it shows how cheap it can be. Bitcoin is better than currency in that you don't have to be physically in the same place and, of course, for large transactions, currency can get pretty inconvenient."

While Gates holds Bitcoin at an arm's length, Microsoft has had a long association with Bitcoin and blockchain technology.

Back in 2014, the company's website began accepting Bitcoin as a payment method, and its cloud computing platform Microsoft Azure launched its Blockchain Workbench that aims to allow companies develop, test and launch blockchain applications.

"Now, if you buy something like bitcoin or some cryptocurrency, you don't really have anything that has produced anything. You're just hoping the next guy pays more."

Surprisingly, Zuckerberg has hardly been quoted in the media when it comes to his views on Bitcoin, cryptocurrencies and blockchain technology.

It ends up painting all cryptocurrencies and blockchain-based services and companies with the same brush, denying them one of the biggest advertising platforms in the world.
