The ICO process itself, which creates new tokens, can not be called a Ponzi method or scheme, although it is used by many for fraudulent purposes. This is a very necessary and useful process for all to create new tokens, which are generally very useful for people with their specific functions, unlike coins, which usually have only the general functions of the means of payment.
The ICO process has never been conceived as a means of fraud, it simply needs to be regulated in the future in order to make it more transparent and protect the rights of investors.
