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?
There are always reason why devs change smart contract from v1 to v2. For some projects it is to enhance more features to the new contract, for some it is to protect the project (if dev notice any vulnerability). while some its to enable the contract to perform more functions (especially gaming platforms). And yes some projects do this to scam bounty participants, they send v1, create v2 and ask users to swap 10% monthly.
