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’s a two reason, either to improve the project by using other contracts or to scam their investors.
There’s a lot of situation like this before and some turns into a scam project after collecting money from the investors. This is why we should always take profit with our bounty reward since not all can sustain their momentum in long term. If you see a project change into another contract better to analyze it, and know if its still worth it to hold that token.
