Kindly explain. The one that i'm confused is not the "burn" after ICO but rather when its established.
AFAIK "burning" is to decrease circulating supply and (supposed) to increase price (assuming constant demand). I believe this is why investor benefits from the activity.
The requirement to burn is to own the coin and send it to unspendable address. It is clear that the coin is lost. Afterwards, the value of burned coins transformed to an increase in price.
However, who does it? And why they do it if they are losing their possession?
