Recent news of the imminent closer of many Chinese exchanges is the direct result of them dealing in ICOs, I've been shocked for the longest time other countries have done so, allowing ICO's to fly under regulators radar, however its only just a matter of time.
It is not all about the exchanges dealing with ICOs, it is about China's great fear on the threat and uncontrollable nature of the cryptospace.
BTCC which announced that they will close in 2 weeks does not have an ICO listed in their exchange. Why were they the first one to close down?
