This is very possible. The Blockchain technology is a revolutionary one with a lot of significance. As the people become more familiar with it, the adoption and utilization of the Blockchain and cryptocurrency will increase which will gradually lead the world to cashless.
What do you mean by "making the world go digital" exactly? Isn't most things already digital including money? Blockchain is an incredible tech and banking institutions are already starting to implement it, but the way they transact with money is already mostly digital. Most of the money in the world is just numbers on a screen and if probably even 20% of people tried to withdraw their money out as cash it would crash the economy. One thing I like about bitcoin though is you can't create money out of thin air or spend money you don't have, but that's where banks make their money.
Almost everything in our daily lives is digital and everything works within a click of a button that makes our daily lives even better and easier. The only negative thing with this digital technologies is the fact that they make humans lazy to do things or tasks manually and they have the feeling that they will be unable to live in this world without this digital objects and machines that make a task easier.
We are heading to a cashless society with or without the blockchain technology. The internet and computer technology is gradually making cash unnecessary to carry about.
As one can use Internet and mobile banking.
Also debit cards. Digital currency can only facilitate the digitalization of the world.
Bitcoin offers a level of control to individuals that can not be gotten from any other financial sector.
As you are completely and solely responsible for your assets.
Our world is really changing but I hope people still don't forget the values of life and how to appreciate things because most of the people these days do not give value to the old ways that we've used to use or do.
