Facebook's Stablecoin

Facebook is developing a Stablecoin that will be tied to the value of US dollar. As you can see by its name, these coins are meant to be more resistant to volatility than bitcoins. The company already has dozens of online merchants and financial firms to support thier cryptocurrency-based payment platform on its mammoth social network. Il will enable users to transfer money via WhatsApp’s encrypted mobile messaging service.

What interests me more of their cryptocurrency ambitions is that Facebook plans to reward users with fractions of Stablecoins when users view ads or shop on its platform or turn them over as loyalty points for shopping on its platform. And if a user clicks on an add and buys something using these coins, the retailer could then use them to pay for more ads, etc.
The system also want to be a checkout options that people could use across the internet, such as PayPal, and this idea seems to me not much different from what’s happening in steem ecosystem and what users here have dreamt, namely extending purchases with coins in online/offline market. So I’m wondering about its future implication, if it would be generally of help to all crypto-based payment systems, or be a threatening rival who want to monopolize. What do you think?
