As soon as majority of the world is informed and knows about digital currency, what do you think will happen? No matter how good it sounds to traditional banking, how much of the population will make cryptocurrency grow?
Honestly, I think that there would be lots of dramas as we grow in numbers. Just like in everything else, humans tend to destroy things over simple and silly stuffs. There would be people, might even grow to teams, spreading FUD out there just so they can pump/dump the coins that they like. People will be busy trading. Never have I seen a bitcoin user that didn't eventually go full time on trading by quitting their day job. I guess it's because we have very low pay rate in my country but I also talked to some people in slack. They also quit their day job to go all in in making money from cryptocurrencies. We all want a money making method in which we can decide when to do work, and when to take a rest.
