Would writing one's own cryptocurrency in a language other than C/C++ be stupid?

I am curious from a overall performance perspective if writing a cryptocurrency from the floor up in a language apart from c/c++ be silly?

For example, if i desired to jot down a ethereum smart futures and protocol in python or nodejs, could i run into overall performance and speed issues later down the rode considering the fact that those languages are not as “low-level”?

or are there another troubles besides overall performance i would run into?

any suggestions are appreciated. Thanks!
