Wholeheartedly agree that cryptocurrencies haven't found a good (legitimate) use in the past 10 years. However 10 years is a short period especially in fields that grow exponentially overtime. I feel the real use cases and technological advances in the cryptocurrency field are just starting to take of. We see all kinds of domain specific applications popping up (e.g. IOTA which tries to solve problems in the domain of machine-to-machine economy). I hope cryptocurrencies will be the backbone of the fight against a centralized/walled-garden internet and will help us decentralizing the internet in the next 10/20/30 years.
