Fb coin for sure will become really popular and for sure you will earn more money once you invested. I see last year when I see advertising to the fb of crypto is banned so that's why the facebook now creating their own coin and I hope they will have good effect of having fb coin now.
I also remember that, when Facebook banned all ads related to crypto. And now, they plan to have their own coins. Although this information need more confirmation, but many large companies that support crypto will be more positive in the future.
