Ethereum (testnet?)
I'd be surprised if they were even that far to be honest.
I think crypto 1.0 currencies can still work with the right community and right infrastructure built on top of them to make them easier to use as currencies for regular people.
Crypto 2.0 style currencies are great, but there is also an added element of risk considering they are still new and yet to go through the rigorous testing that Bitcoin has gone through over the the past 5 years+. That can't be dismissed completely I don't think.
