I am sure that if I had known before how you treat investors, I would not have participated in this ICO. The explanations that are giving most affected are reasonable, ¿how can you change the rules of the game in the middle of the game? this is not ethical.
It seems good to me if you want to expand your project if you have growth forecasts, but it is not good to reduce our value, you have no logic what excuses you are giving.
