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 it will not happen any time soon. Because to realize it first of all the digital currency must be accepted globally. But I believe blockchain technology will be adopted globally in the future.
