IMO, the killer app for cryptocurrency is going to be open bazaar. What is open bazaar? Simply put - it is a peer to peer decentralized market place. Think of a something like amazon except no fees to sell, no restriction on what you can sell and powered by bitcoin. Right now the software does not work fully because the only crypto you can use it bitcoin which currently has high fees. The devs are going o switch to using bitcoin cash which has low transaction fees (pennies per transaction). I have bought and sold items on open bazaar when it was working and it works flawlessly. The buying and selling experience is by far the best I've had. Since there are no fees (other than transaction fees charged by BTC/BCH) you can make more profit compared to selling on ebay/amazon.
