More than 50% of the world's population of this world is desirous of having crypto currency to be used for their daily transactions. But there is a part of the population who isn't ready to accept the crypto currency because they do not see it as a pleasant change. And also there is a part of the population that isn;t aware of how well the crytpo market can be explored to its full potential.
The question is a bit ambiguous and I don't think there is a clear answer. It's as if someone had wondered years ago if the world was ready for smartphones, electronic money, go shopping and pay with the mobile phone, etc. These tools simply appeared and people started using them. With cryptocurrencies something similar will happen, in fact, it could be said that this process has already begun although it's true that it's being slower than we would like.
Exactly, this change will slowly sweep over a period of time and will become a part of our lives. But there are many obstacles to this becoming a reality and it is a long process. Let's see what the future has in store for us.
