A very correct approach for designing a bounty. Not more than 2% of tokens are allocated. Thus, they not only save the budget, but also insure companies from bounty hunters who immediately sell to the exchange tokens
Yes, the approach is correct. I often met when companies allocate 3-5%. I think this is a lot, and there are fears for investors - the token price may fall after entering on the exchanger.
I think that not all bounty hunters are so stupid as to immediately sell a token that list on the exchanger. It's not very smart, because with time the price will rise!
