Fortune magazine recently released the "The greatest designs of modern times" list. "Bitcoin" was selected and ranked 90th. IDEO founder David Kelley gave Bitcoin a comment: Bitcoin is designed to allow a wide range of stakeholders-developers, investors, companies, miners, and individuals-to use an incentive mechanism. Adopt a brand new digital currency without the need for any centralized issuer or management agency. In the more than 10 years since its release, the value of bitcoin has been close to 200 billion US dollars (note: after the sharp fall last week, the real-time market value of bitcoin is currently 94.9 billion US dollars), which is used by millions of people around the world. I don't think any other product in world history can guide itself so effectively.
