Sixth paragraph down, here it is:
“So far, one feature has been more important than any other in helping any altcoin build user buy-in: honest, transparent, and relatively selfless behavior by its developers. Litecoin lead developer Charlie Lee made great efforts to ensure cryptocurrency supporters’ awareness and access at Litecoin’s launch, when any cryptocurrency is easiest to mine. “I released the source code a week before the launch [in October of 2011], so people could prepare [to mine].” In part thanks to this push for fairness and openness, litecoin is now the second-biggest cryptocurrency after bitcoin. Creator Sunny King similarly released the sourcecode for his peercoin nine days before mining opened in August of 2012. Peercoin is currently the third-ranked cryptocurrency”
