Basically, crypto is new and any doubt that it is a big part of our future is a typical part of anything that is new and groundbreaking. To see where this is going requires 2 main things - open mindedness / vision, and a strong knowledge of disruptive technologies that have succeeded in the past (know the history of tech). I can say with confidence that crypto is perhaps one of the most powerful technologies that have ever come our way in terms of how rapidly it is embedding itself in the very fabric of our society. 'Fads' do NOT get regulated by governments around the globe. The race for the first cryptocurrency that will be truly adopted is a crowded space and the growing efforts in this landscape is one of the MANY reasons crypto will thrive.
