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 think bitcoin cannot replace the paper money thoroughly.
There are banks that distribute paper money.
Meanwhile, banks will remain in different countries to perform their roles.
