According to this
news article, FB is allowing dogecoin, digibytes, einsteinium, fedoracoin, mintcoin, reddcoin, quark, worldcoin, vertcoin, karmacoin, earthcoin, trollcoin, HTMLcoin and donationcoin. I wonder Bitcoin is not in the list !!! Does it mean that Facebook board of directors understood they are a bit late in Bitcoin mining and hence mined other alts and now boosting those through their platform for quick profit ?
p.s. Juck wont probably like Bitcoin as Winklevoss hold 1% of it.
