Did we all already talk about https://initiativeq.com ??
Well, according to the site, a bunch of ex-Paypal guys got together and started (or are starting) a new Cryptocurrency. The name of that Currency? The "Q". The goal is to have 1Q = 1USD.
I just thought it was a bit interesting that of all the things they could name a cryptocurrency, they went with Q.
I couldn't find anything on their site specifically signifying why they called it that over anything else.
