I agree, Ethereum is an example of something that took the concepts underpinning Bitcoin: distributed immutable legder and verifiable trust and created an platform that I think can be very interesting for building decentralized marketplaces. The technology is new so there are going to be hurdles but in terms of scaling and obviously a lot of speculation, but I think there are also a lot of socio/geopolitical factors that will continue to make cryptocurrencies a thing.
