If ICO was banned in China therefore altcoins will be affected not the bitcoin so i would say the whole cryptocurrency would be the issue here. But i believe bitcoin will not going down that this declining value trend that is happenning now is just a temporary because of those panic people. If the bitcoin will going down at $2,000 it will be my chance to purchase while it is in the cheaper moment. Lots of investors out there are waiting for bitcoin to become much little cheaper so that they can buy a huge amount again.
