Ok, now this would be kind of wild. Is there any real substance to this acquisition rumor? It's one thing for Facebook to want that easy money from the adverts, but it's a whole different ball game to want to get into the crypto space like this. Why wouldn't they just roll out their own crypto?
Difficult to imagine Facebook shilling crypto (as opposed to its advertisers shilling crypto, which it can profit from without taking responsibility for) ending up in anything other than tears and class action lawsuits...
