Well, every crypto currency has it's own characteristics. And therefore different USPs. I don't expect currencies that involve blockchains to be the dominant payment channels of the future. For payments, I expect simpler constructs. Lightning Network already handles most transactions without blockchain interaction. And Iota is a completely blockchainless currency that got traction already. I think there will be many more approaches before one becomes the 'everyday' crypto currency.
