All people need to subscribe for an internet, Telcom Industry will boom this way, since everyone needs an internet to make a transaction with bitcoin or connect to its network. Just for example in my country, there are few places where interenet is free and the worst of it is that your connection will drop after 30 to an hour depends on the host. And internet provider in my country charges too high. So in a scenario where blockchain become mainstream, the TelCom company will profit the most.
Yeah. That would be the main focus as the internet will become more a necessity towards communication, entertainment, and now transacting over it. Basically, the internet would be used practically for anything and it will grow even more once it transitions to the blockchain ecosystem. Just wait and see when Maidsafe gets the official stable release and we'll be one step closer towards decentralizing the internet and making it even more useful for people around the world.
The blockchain will change everything in our daily lives from transacting, to smart contracts, to decentralized internet, and more. I think that these 7 years since Bitcoin and blockchain's inception are just the beginning. Give it a few more years and it will boom! Just my opinion.
