Perfect bounty campaign includes several points. First, its tokens do not fall after entering the exchange, but grow. Secondly, these tokens themselves should be credited quickly and without cheating.
In my opinion, more than 70% of the bounty tokens have depreciated after going public, and the depreciation is very large. For bounty hunters, if you can't sell your tokens in time, they will soon Will become worthless.
Of course, I have also seen a few of the bounty tokens that they have risen after listing, but this is very rare.
