Can a Butterfly Labs Jalapeño be used to mine Zetacoin? Can my Butterfly Labs Jalapeño be switched to mine Zetacoin?
Bitcoin ASICs like the old Butterfly Labs Jalapeno can do one thing and one thing only and that's SHA-256 hashing. Searches indicate Zetacoin uses SHA-256 hashing, so the answer is yes. Whether or not you will make any money is whole different story.
