How do you know if it is a scam? Because I have encountered a bounty that let me finish all the translations first and didn't respond to me after I have passed it. I hope bounties will not be like this anymore because they demand and we did our part but they didn't do theirs. I hope you could answer my question.
I recommend that you carefully consider the selection of a suitable project to minimize your possible risks. For this, it is necessary to study the data on project documentation, the development team, further development strategies, as well as third-party ratings and expert opinions.
