it is non profitable for FB
Its temporary and they are looking for new ways to get rid of scam projects,but its unclear why they banned bitcoin.it may not be groundless that they are going to remove ICO ads because they dont have any sources to detect which projects are scam or good.I remember one of the crypto startuper had earned millions of dollars and after this they just dissapeared with swearing and mocking,as i remember it was Prodeum ICO.So the reason why i told you guys this story is that people need preventive measures because some of them are not as good in this sphere as they think
