I wonder what place they will take on the coinmarketcap? Will they easily dethrone bitcoin or just take the 2nd spot from Ethereum? But man, Facebook will work as a jet fuel for the cryptocurrency huge take off into the moon. Because there is no way that bitcoin will not get paired with that FB coin on all of the exchanges.
I think it's difficult to overthrow bitcoin because in my opinion bitcoin will still be number 1. which I know maybe fb will become Ethereum competitor. that's just my opinion
