That's a rather bold claim. What you call cryptocurrency is an ERC-20 token intended for experimenting with community economy (e.g. tipping contributors, voting for features, app market, etc). It's an untrodden path and the idea is quite interesting in its own way.
Regardless of the blockchain involvement, I encourage everyone to stay open-minded and judge the project on its technical merits.
So the cryptocurrency stuff isn't at all part of the language or stdlib?
What makes you think it is? There are plans to offer a lightweight console module for the Ethereum scheme and C3 dialect, but since there's very little interest in this branch of development from the community (and a lot of skepticism with nay-saying) it's not a priority.
I don't think it is, I (and I assume many developers) just want to stay far away from anything cryptocurrency-related.
