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...
Lol! This is basically your own perception but not the general view of thousands or should i say millions of people still using facebook till date, this is business where people will have the opportunity to earn profit if it is available, i don't think the few accounts that were banned will have a dent on Facebook intentions, when eventually this comes to reality, watch and see how crypto community and the non crypto people will react, money has power, you should know that.
