You are correct, the time that i read the news that they lifted the banned on promoting ICO's in facebook, i just immediately think that they are now recognizing the good side of blockchain technology., blockchain will replace the old techniques which are used primarily on some major businesses, but its good to know that they are considering blockchain as the new emerging technology nowadays. Its makes life easier and it does lessen the manpower resources., if it will be properly implemented to everyone.
Hoping that this entry of facebook, they could serve the community a lot more better than the old ones. Its makes me excited, how they can applied to existing applications.
