"Largely cryptos until this point have just been a storage of wealth and had little to no real use cases"

Being able to send value anywhere in the world without an intermediary isn't a "real use case"? Bitcoin has only become a legitimate store of value somewhat recently as it's become more stable in price (although it's still quite volatile for a store of value).

Sure, blockchain technology can be used for more than just digital cash, but there's a good argument for digital cash still being the BEST use case. Once Bitcoin can stabilize in price enough to be trusted by more businesses as a legitimate currency (that the money they accept from customers today won't be worth less tomorrow), and solve some of it's scaling issues, it will have realized Satoshi's original vision. I don't think this scenario is too far off.

Ethereum realizing it's dream of being the foundation of Web 3.0, however, seems further off. It's an amazing vision, and I think we'll get there eventually, but given that right now the majority of transactions happening on the Ethereum blockchain are related to ICOs, and the fact that many of those ICOs are for applications that gain little to no advantage over their centralized competitors by being decentralized, we're still a long way from achieving it. I think Web 3.0 has bigger roadblocks than Bitcoin revolutionizing how we think of currency.
