Hackathon project Wificoin wants to help people buy or earn access to hotspots nearby using Bitcoin or Ethereum: Wificoin first installs its open source operating system onto a Wi-Fi router. When new users connect, they get 100 Wificoin, which they can spend for one megabyte each of Wi-Fi access. If they need more, they can either buy Wificoin with cryptocurrency, or they can install the software on a router they own which earns them Wificoin each time someone uses it. Thanks scojer.
Eventually, Wificoin wants to let people buy access with traditional credit cards. It also plans to allow people monitor their bandwidth, and switch which device you’re using to access the Wifi by authenticating both through Facebook. One of the biggest opportunities for cryptocurrency is the ability to transact micropayments without a high processing fee like with credit cards. Even if you only wanted to buy a few megabytes of bandwidth for a few cents, that would be feasible with cryptocurrency transfer when the fees would normally wipeout the profit for the seller.
