Korea gov is friendly with USA gov so I think they will just control ICO. not ban it. many good ICO from USA still coming
Most of the icos does not allow US participants
Are we gonna see ban on exchanges too?
I don't think that it will happen, South Korea is doing a good job on regulating Bitcoin it is for their own security and in order for them to prevent money laundering acts. It is better to regulate bitcoin rather than banning it.
