Too late. They most likely missed the crypto train. Banning crypto ads and accounts damaged their reputation and it wasn't already in a good shape before it.
It will still create some hype however. It still has a name which is worth millions of dollars. Just a name...
They made a big mistake because they were banned crypto ads, now they want to make coins so it's like a funny thing, maybe this will be a failed project for them.
Failed project for Facebook? Do you think people are interested in pay back for something that will eventually benefits them.
Facebook already has a name, and if peradventure they truly announce their intention on creating a coin, a lot of people will be happy about this development, at least now that they have joined in the adoption stage too, they will have no reason to ban other ones, people are strictly interested on what they can benefit and not what Facebook stood against, I was not happy too during those time they were banning some crypto accounts but if I see their coin now, I will invest massively in it.
