Even with China Usa banning ICO, they cant stop people to invest into them, bitcoin does allows them to keep investing no matter if their country does allow or not. Ico will still being promoted and be made untill the day the market is full and all potencial projects get live, there is no way to stop them, as some of them does bring interest and value to crypto.
In theory, they can't totally ban ico concept. We use digital and virtual coins where we can do our wishes. They can't control our virtual coins from their central governments. So I'll keep participating in different icos.
ya but if ICO is illegal in they country. They maybe get jailed if they invest on ICO. it's still bad for some trader
