actually, there is nothing wrong with participating in many campaigns in one or many projects. we are not forbidden to do so as long as we know the risks. because not all projects pay, we must be selective in choosing.
working on a bounty campaign should be different from an airdrop campaign. because the bounty has more tasks and campaign types. following a lot of projects, I'm sure it will be very inconvenient for some people to work on it.
I agree with you, we have to be more selective about the projects that we will participate in, because the possibility of the project will only be a scam. It's a shame if we are tired of thinking about being disciplined in carrying out tasks in the bounty project and at the end of the allocation we don't get anything, considering that the tasks in the bounty campaign project are more than the airdrop campaign project.
