Personally I say yes as our society becomes increasingly dependent upon technology, digital currency will become a more popular means of paying for different things and it is more effective and instant. I haven't used much physical money in the past 8 years and I rarely had any problems with that.
What do you guys think?

I don't think digital money will replace paper money. Digital money is now accepted and widely used in some countries around the world. But it has a lot of flaws, it needs the Internet, and I don't think people around the world are using the Internet, which will make it impossible for him to replace paper money.
