Yes this is very true, in Zimbabwe we call it plastic money.The shortage of the us dollar which was adopted by the government is now vivid.Most transactions are now mobile in Zimbabwe.However most folks are still used to cash,the early adopters of plastic money have been the youth who understand and see the the future of digital currency.The other day my friend told me he had $3000usd worth of bitcoins and i was shocked because i also thought bitcoins and crypto currency were fake.Having been introduced to steemit.com now i can see the endless possibilities.Digital currency is the future and the future is now.
