Another fud to bring the cryptocurencies down. I think we should see this as another attack and bitcoin price may come down because of the way many people on Facebook may interpret this. Bitcoin and blickchain technology can been used for scam but that doesn't mean any other forms of money can also be used for scam and fund raising. Facebook and Microsoft were in favor of bitcoin and other cryptocurencies before but lately there have started to attacked it for the reason best known to them.
yeah i think its a fudd people dont hesitate to use facebook to promote or advertise bitcoin and other altcoin.
Actually many are ban on Facebook,it's OK to promote ICOs and project but the other users is abusing it's use as spamming of post so you need to be careful when you use Facebook to promote follow the rules to avoid abandonment of your account.
