check out maidsafe coin it is just a proxy coin right now but it will be exchanged 1:1 for safe coin when they deploy their network. They are basically trying to build the decentralized internet with decentralized web hosting and storage and decentralized apps. it can replace all those companys that charge for web hosting or cloud storage since it will be cheaper to host or store on their network and it will be alot more secure. and it can have decentralized apps like ethereum so if someone wanted to make a Facebook app on there it will be alot more secure than Facebook because the NSA won't be able to snoop on your private messages or calls
