If you are not sure that investing in ICO you better go to the Crypto market. And buy coins that are already established and have a large trading volume. It is indeed not easy to invest in ICO because many ICO projects are a scam. So many people hesitate to invest.
ICO is getting worse and more people are inclined to invest in IEO and STO because this is a new revolution in this market. It can be seen that the IEO has been very successful in recent months because almost all IEO projects are sold very quickly and have achieved great success. I believe in the future we will see many more good projects and the IEO will completely replace ICO
