Facebook is the catalyst which will change how Cryptocurrencies are seen and used forever.
what would be the difference between Libra and other stablecoin or other altcoins? I'll answer that question:
The answer is very simple, facebook is popular and has popular partners, but that does not mean that your currency will be a great success... you know what the biggest problem in the crypto world in my opinion? create high expectations. Thinking that because facebook has thousands of users and because of that will be a great success, is an illusion.
How many facebook users do you think will use Libra? and why would they use Libra when they can use Fiat in their daily lives? many facebook users are people who are to post photos and videos for exhibition and fame, they are not to make investments or spend money on facebook
