Would writing one's own cryptocurrency in a language other than C/C++ be stupid? I'm curious from a performance perspective if writing a cryptocurrency from the ground up in a language other than C/C++ be stupid?

For example, if I wanted to write a cryptocurrency and protocol in Python or Nodejs, would I run into performance and speed issues later down the rode since these languages aren't as "low-level"?

Or are there any other issues besides performance I would run into?

Any thoughts are appreciated. Thanks
There's no reason why a cryptocurrency needs to be written in a low level language. It's just that Satoshi's original implementation of Bitcoin happened to be in C++ (perhaps that was the language he/they felt most comfortable with), so now a lot of people seem to think it has to be that way. It doesn't.

You could certainly implement a cryptocurrency (either an existing one, or a totally newly designed one), in Python, or Javascript, or pretty much anything else. Wallet software is mostly managing a big database with a bunch of hashing.
