Why are you planning to issue such a large number of tokens?

The quantity is unimportant, the main thing is to have a stable price policy of the token.
If the tokens are not all sold, then they can be burned so that the price does not lose gradually and there is no fall
This is done so that bounty hunters will immediately sell it at a minimum price at the exchange, so that its price immediately starts to drop
I do not quite understand the course of your thoughts. And then, bounty hunters to burn unsold tokens? These are completely different things and are not interconnected. And no one forces bounty hunters to sell tokens very cheaply. it is their personal choice.
