The real benefit is the underlying technology. A currency is more of a basic proof of concept for a blockchain application. There are a few reasons blockchains are a game changer for decentralized apps. 1) It's vastly more difficult to cheat. (remember lying bittorrent clients which would break the rules to improve your download speed by spoofing your ratio?) 2) There is a built in system for compensation. 3) Writing a distributed application is very difficult. Platforms like Ethereum, Lisk, and EOS have done the most challenging aspects of this for you and provide varying levels of control vs ease of use via their APIs. Valuations of the currencies are dramatically inflated right now but no matter what happens to price in the long term the underlying technology will be revolutionary even if every currency fails.
