Internet was also faced with almost the same challenge. During the advent of internet, people were nit ready to accept it and some said "can we be online without internet?" Despite all these, internet became acceptable worldwide, because everyone has now seen it's importance. So crypto should not be an exception. It is also facing similar challenge now, but it will overcome it.
This is the same with all new ideas and technologies, at first people are going to resist change then they are going to attack the technology in question but eventually they will recognize the utility of the technology to the point that not adopting it will seem odd, for example I do not have a social media account and every time I say that people look at me as if I came from a different planet, and the same will eventually happen with cryptocurrencies.
