Don't be very optimistic about this coin. It can do more harm to the crypto market than good. A large chunk of the current crypto market can shift to this coin, given the huge user-base that Facebook is having currently. On top of that, Facebook may try to monopolize the crypto-market, by destroying the other cryptocurrencies such as Bitcoin and Ether.
shorting or simply people mostly on crypto will just jump in for the sake of profits.Ripping off money for those newbie investors of this coin who do just been
dragged out on the hype but for those people who are aware on potential will always come back to btc.
I don't really like a centralized coin because they can easily take it out to you without your consent.
