who said it is?
the only reason why there is a lot of talk about it is because of the news sites that were desperately waiting for something to write about and that has been bringing a lot of newbies attention to this coin, which in my opinion should not even be called a coin. we should call it a centralized online payment processor.
by the way it has nothing to do with price and bitcoin is not an investment, if it were then its price would have tanked hard a long time ago just like how altcoins get dumped and never recover again since altcoins are purely for investment and have no other usages.
Every website wants to join the bandwagon. Just to say something even if they don't know what they are talking about. For sure, most of them don't know how to transact any altcoin out there. We should not take seriously all the fuss they are making out of it. And on my end, FB coin will never be a threat to bitcoin because they are totally different in nature.
