Why? NEO can just systematically exclude Chinese people to participate in ICOs if they want to and it's easier that way, just to not be under Chinese jurisdiction. Or they'll comply with the regulatory in place.
how can a platform systematically exclude people? I dont think you understand how any of this works. Exchanges are the ones facilitating ICOs, they'll just exclude people from certain regions like they have already been doing. The issue is that it prohibits the people in China from buying or continue to buy into these projects. The same thing happened with Bitcoin in 2013 when China took a hard stance which crashed the price.
