I have been looking into the algorithm called blowfish, it looks very interesting. I had to try to break some salted hashes with it a few days ago and it was so slow, I could only get around 40hash/s with my i5 and even less with my GPU. I doubt I could break in any time a 5 character password with it, it is very secure. From my understanding blowfish only works well on CPU's. That would be a good algo to use, I wonder if any other coins use it.
should consider an algo , which is more widely applied.
so far as i know, CPU coins are not very popular, not so many people mine it.
i dont mind scrypt, RZR is one of scrypt coins which is doing well recently..
we should think up some more creative ideas,, algo is not really matters.
