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?
Its a good idea to burn tokens that aren't sold in ICO but at the same time it depends on the max supply of the token, if its in billions burning will be better, not all projects prefer this but few ones who did have good end results
