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.
And there are the signs of Bitcoin worthiness. Government will not battle with the thing that making no difference, so for me it's only assured me that bitcoin is our future, and we need to fight for it.
The banning of crypto currency ads on facebook and other social media is also benefit in a way as people were falling victim of scam ico through their attractive advertisements. Now the ordinary person will not fall for it as there will be no such ICO ads. Its is good in a way to keeps scams out of digitial currency world.
