There are 3 major exchanges in china: BTC China, Huobi and OkCoin. Only BTCC allow ICO trading and it's the only one closing. Maybe it's related to the ICO ban from last week and nothing to do with bitcoin
If that's how Chinese exchanges interpret it also, this will have a huge impact on some of the largest miners and mining hardware companies (lie BitMain).
