As a bounty hunter, I will definitely be happy to receive the results of the campaigns that have been followed in this forum, but I myself am confused why the Owner always replaces the smart contract even though the token/coin is already known. what is the meaning of the tokens that have been distributed to participants, is it just for fun?
They change and sometimes changed back again and this kind of matters only the team knows the reasons behind it and as a bounty hunter, all you have to worry about is your payment and how effective you promote their projects. You don't need to worry about such things because this kind of matter is for the team only. Just follow their instructions on how you will gonna withdraw your rewards and I'm sure most of them won't let their bounty participants down after all they are one of the main keys to why their project has earned popularity.
True, but the important point here is that the value paid to participants after the campaign ends is very much different and very low than the value of the new coin that has changed its Smart Contracts.
