A large majority of peoples in the world believes on paper money. They think that this is used for buying or selling goods and services. A currency which has a physically appearance in the world.
But the upcoming world is the world of digital currency. Because it is easy and reliable way for sending and receiving money at any place in the world. We can send or receive money within minutes.
But there is a huge difference between both these two types of currencies.
So, it is very difficult that Digital currency will be adopted worldwide. Because of the users are not aware of this new technology and they are not comfortable to use this mode of payment. Because they don't believe in this technology yet.
So, how we convince the peoples to adopt digital currency?

I am glad you took the necessary time to highlight the various differences between paper money and digital money.
As much as digital money has more advantages than paper money, it is still not widely accepted simply because it cannot yet be used to carry day to day transactions. Trust me, it is until digital money can be spent in all stores that it would become universally adopted.
However, the rate of adoption is ever increasing and it wouldn't be long before digital money becomes the norm of the day
