"This is a good thing. China can no longer play with the markets by banning Bitcoin. Crypto-currency cannot be killed by any country."
 
I agree with this  but the only thing make me worried if the countries of the ( euro,Dollar,Yen,yuan) together start making a serious regulation for  bitcoin exchange . otherwise china banning it is like harvey & Irma whatever the crashing causes by the banning ,it  will go
 & the market will be up again,,,,,,,, people trust bitcoin more than any other currency
