If in the plan the coin will be tied with several currencies (stable coins) and with the aim of avoiding volatility, there may not be many interested parties. Actually I am interested and have had an interest in investing $ 700 in this Facebook project and will wait for its launch. But it seems like my enthusiasm is decreasing right now.
I am very certain it will be stable coin too and I am not so sure it will be suitable for investment since there wont be so much volatility in it, so investment in this reject will really not yield so much profit. I will rather put that $700 in other coins that are suitable for investment, or use it to be trading Bitcoin instead, except maybe you are one of the people that use their platform for business, and then you can convert your fiat to their coin, and probably still get very little increase.
I am sure the full details of the project will be revealed officially soon, because I still count all these as rumor despite all the links shown, but none of them has really been linked to the official page.
