I often read and heard about burning tokens that were not sold when the ICO project was finished, I also knew that by burning the rest of the token was a strategy so the price of the token didn't fall, but if the DEV and the team didn't burn it was a crime? is there a requirement that the remaining unsold tokens must be burned?
Where there is no Law, there is no crime. No one made a rule that the tokens must be burnt as there is no regulator for the market. We have several situations where the ICO team share the unsold tokens to themselves, and sell it gradually on exchange after listing. Those are most times the dumped tokens that even kill the price during listing most times. How else would you discribe someone selling a total of 5,000,000 tokens at once at $0.001 per token whereas the ICO price was $0.10? I am sure no investor could have done that. Reason it logically with me. You will find that I am telling the truth.
