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?

Digital money can be a form of payment, but I don't think it can replace paper money. I think they might be there at the same time. The digital currency is now recognised only in very few countries, and its transactions require the Internet, which will limit its importance as a replacement for bitcoin.
