Legendary investor Tim Draper is confident that in five years all will use crypto currency. According to Draper, the technological shift that we can observe now will be more significant than the transition from the Stone Age to the Bronze Age. Answering the question about how he sees the current situation in comparison with the period when he invested in the technologies of web 1.0 and 2.0, he replied that web technologies and transformed the concept of information, while blocking has the potential to transform almost all industries, including government services.
With technology and discoveries in the future I guess cryptos will arise and people will give credit to it and will become credible to people. I hope for the next few years crypto will be known all over the world and government would give crypto a chance to run in each countries.
If anything I suspect that it's more likely that more governments will take a stricter stance and at least try to add more and more regulations. The biggest problem is all the scams and regular people who get pulled in and lose their money. Naturally they end up complaining and wanting action.
