Facebook is working on its own crypto. It will help other cryptos or not?

This is the news:

By CCN.com: The cryptocurrency space is concerned about whether or not the upcoming Facebook Coin will hurt the Bitcoin market. But according to Spencer Bogart, the social media giant’s entry into the crypto space could be the best thing that ever happened to bitcoin.

The Blockchain Capital executive told Bloomberg that Facebook was a significant catalyst for boosting bitcoin’s adoption globally. The social media platform boasted billions of users worldwide. So, even a small percentage of them trickling into the cryptocurrency market could double or triple its user base.

“We have seen public reports of what Facebook might be working on – most of that is pretty private,” explained Bogart. “But what we do know is that they have [an extensive] and serious team that is working on some public blockchain effort – some payment system.

“At the same time, Bitcoin has gone from zero users ten years ago to somewhere between 30 to 100 million – the estimates are tough. And Facebook has billions of users.”

Some analysts think that a Crypto-Fb-coin will dammage Bitcoin and other existing crypto coins a lot, subtracting capital and attention to it. Some other analysts think that it will be the "best think may happen to the crypto universe", making the popularity explode trough millions of Facebook users.
