If is truely happen that that new coin of facebook will launch, I think there is a new competitor or I can say that bitcoin has a huge and strong competitor. Because all we know that facebook don't need to advertise if they launched their own coin because they are already popular so people will surely adopt that coin.
If possible, this coin will certainly have a very large market capitalization and will attract many investors around the world to invest in this market. I think this is a prediction that will happen in the near future because Facebook is one of the top 10 largest companies in the world and GlobalCoin coin will be the most suitable opponent to defeat Bitcoin in the near future.
Indeed, with many users around the world, facebook could be smartest company. When globalcoin launch, investor must be want to invest and facebook marketplace will use global coin. When its already launch, i think invest in global coin is profitable
It could happen, especially if the investor has believed facebook and globalcoin, so they will invest the money with them. But as they already see that many projects became a scam and some of the investor still worried to get scam again. Maybe some of the investors will invest with facebook, and the other will take a look at the progress before they invest. They don't want to make the same mistake as before, and they need to see first.
