Almost ICO project from China always ended crowdsale very fast, maybe 99% project will be end after one day or one hour .
I think the Chinese government see ICO market look like as speculative place and affected their economy, #IMO
Governments--or more specifically, the sort of people who seek careers in government--are all about two things: power and control.
ICOs take away both those things from government powers-that-be. The Chinese are smart though. They know that crypto can't be stopped and, even if it could, shouldn't be. Step one is to attack the established competition. Step two is to co-opt the competition. Expect government regulated and authorized crypto coins and ICOs to come in the near future.
