They don't exist. It's not 2017 any more. No one (serious) is trying to build the next Bitcoin. The vast majority of the crypto community has moved on from "cryptocurrencies" to "utility tokens". People have moved on from projects like Litecoin, Vertcoin, and even Bitcoin Cash to projects like Filecoin, Gridcoin, and Helium where the purpose of these tokens isn't to replace money like Bitcoin (and its many failed rivals), but to create incentive structures to support and sustain whatever decentralized solution they've built (cloud storage, computing, and cellular network, respectively for the aforementioned examples).

I'm painting with broad strokes here, or course. But everyone I've talked to that's working in crypto and isn't a CEX trader, this is basically where they're at. They hold bitcoin, and they're all open to a future where goods (and their tokens) are priced in BTC.
