Greetings @neavvy thanks for the invitation to give my opinion / comment in your post, first of all very accurate and simple.
Basically my thinking about Libra (without going into conspiranoid things) is that they (Facebook) are somehow trying to extend their reach in what is the market of sales of things (not as advertisers but as already action of change ) and have noticed that they are used in certain points or in some places cryptocurrencies (example of it, the Dash, ethereum, etc etc) at least here is something common to see people accept them.
And they notice that there is also gain in being part of that environment and if your conglomerate already enjoys millions and millions of active users with this they go home with full bases, I mean, they put minimum quotas for operation and in the long run the investment would be good.
As for fixing the currency to existing ones I do not know why I remember what the usurper (Nicolas Maduro) does with the petro (a coin more false than a $ 3.33 bill) but maybe they do it to try clear people's minds of what could be an abrupt change in the price of their currency, because as we know the coins can go down or up overnight and I do not think that people who just want to enter these seas be willing to that.
And is that I speak more than anything about people who do not know much about the subject but who know or have heard of the volatility of prices in cryptocurrencies.
In particular as the saying goes dawn and we will see, I'm sure that as it will bring benefits will also bring cons and more than anything by people who seek to get the accounts of others to get some money.
No more to add, thank you for reaching this part of my comment, and I do not leave without first wishing you a good day afternoon or evening, happy start of the week, God bless you.
Thank you for your amazing comment @jjqf. I appreciate it a lot.
You are right. Facebook and other big companies have noticed that there is a big market growing apart of them. It is reasonable that they are trying to take advantage.
Thank you! Wish you a good day too :)
