Hi Chance567
I don't think decentralisation is a prerequisite for a cryptocurrency. I'm still a newbie and have only just received my first payment for mining Litecoin, but from what I can tell XRP - the money used by Ripple (currently 2nd in market Cap to Bitcoin) is a centralised cryptocurrency.
I'm mainly just sayin this to fill in the page and potentially as a point of discussion.
