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?
I'm also very curious about that, how can we know they will burn tokens? It is very difficult to know exactly that, most of us just participate in trust
