Fraud among projects using standard tokens ERC-20 is really a lot. That is why the development of a new token standard is underway that will allow investors to withdraw their invested funds back if they are not satisfied with the state of affairs in the project.
I wonder how it will look? If an investor made an example of an ethereum on a smart contract as an investment in a project, and then took and changed his mind and took his money, then how the project can develop in such conditions.
