PDCA (plan-do-check-action) Diary Vol. 656 "Will the day when the coins vanish someday?"

The material introduced today "Hard-Boiled Wonderland And The End Of The World" is one of the masterpieces of written by Mr. Haruki Murakami.


In this book, there is a scene where the main character counts the coins in his pocket, and I like this best :-).


The main character of this material says that he is training his brain by counting coins in pockets with just the touch of a finger without using vision.


Japan used be a cash dominated society, but the use of credit cards has recently increased.


In Scandinavian countries, people are paying with credit cards, and you can live without using cash or coins, and there are some banks that refuse cash.


When people who are born 50 years later might read this book and feel that "What is a coin?"😊.


Let's function PDCA today!

P.S. Crypto asset (virtual currency) trading has recently begun to become active.


In the past, there were times when Bitcoin payments became possible at consumer electronics mass retailers in Japan as well.


However, the boom has slowed down due to a series of accidents such as fluctuations in the crypto asset market and illegal outflows in 2017.


As the prices of crypto assets such as Bitcoin began to rise in the latter half of 2020, traditional financial institutions such as securities companies and asset management companies have also started trading crypto assets.


It is not known at this time whether crypto assets such as Bitcoin will be shaped like fiat currencies such as the US dollar, euro and Japanese yen.


However, it is certain that the electric cars provided by Tesla can be purchased with Bitcoin, and crypto assets such as Bitcoin are beginning to play a role as currency 😊.
