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.
You have a point though about the news , maybe causing a drop but I say that must times, the news we expect to cause a downward might not really be that way. Last year, when the news of Chinese ban on icos hit the air waves, it didn't cause any drop but, a further push upwards. I hope it does not bring the coin down this time.
