how badly could banning of bitcoins in china affect the bitcoin market and cryptocurrency?

Well you have seen it on the last dump of bitcoin. Its because thr government of china are banning the ICo and stop all cryptocurrency exchange that impact to massive sell on that big country. The massive sell caused the bitcoin price to fall down from around $4.8k to around $3k. Its become a prove tht china have a big influence to bitcoin price. But I hope after they banned it, the crypto currency especially bitcoin are free from china influence.
