SHIT sounds like a promising project with an important concept. I'll be keeping my eye on it over the next few days!

It follows the same pattern as FUCK coin and when FUCK coin was first introduced people have similar concerns and it turned out be a success later

The name of the coin is disgusting.Why develop such a coin?I thought it was a joke.

I do not understand why this spam thread is not deleted by moderators?
