The Chinese government banned ICOs. Naturally as a result, alt coins started dropping. People are fearful they won't be able to get their money out with the government cracking down.
For the next couple of days I think it will blow over and go back up, but only time will tell.
I agree with you that if one industrialized / developed country have fallen the ICO everything will in account will also fall. But it does not mean that bitcoin is fail and will be stable as falling down in a London Bridge, I know maybe time will only tell when will bitcoin will rise and gets stable and up again.
Mate really, I am now very much done with this thing. Bitcoins prices have nothing to do with the banning of ICOs by Tthe Chinese government so there is no need to create a fuss out of this because it is spreading fear in people. 80 percent of bitcoins trading is held in China. China supports not only bitcoins but the other crypto currencies also. The downfall in price is not a consequence of that political move. It was happening even before this news.
