I think bittorrent solves actually does solve a problem most people have. If we lived in a bittorrent using utopia, you would never have to set up a web server because you could just seed static websites from a couple home computers. Popular sites would never go down due to DDoS because their users could support them with their own bandwidth. I think that's the idea behind the newer protocols like IPFS. I think cryptocurrency could be used to solve a micropayments problem, but I doubt it will ever catch on if it depends on internet companies' forward thinking and benevolence.
