Not all , it's not regulated in some countries , like Russia.You can still join in some icos .I have to tell you ico is harder to be listed in exchanges, that means ico is far away from quick profit .
thats true, i think just because one country forbids ICO circulating in their country does not mean the future of ICO is over, i think it is a misguided generalization there are still many countries that do not prohibit and have regulation like china. besides that the ban from other country will not any mean to another country
