I quite share you sentiment on this very issue. I am not too convenient with the elongation of ico projects, it might actually profit those the team but not the bounty hunters reason being that as the bounty period is being extended, it will avail more participants to join the bounty thereby increase the number of participants causing a reduction in what a stake should have been.
Yes, I agree with you. The extension of the bounty period will be very beneficial for the project, but vice versa for the participants. The length of the bounty period will make more and more participants and will indirectly reduce the number of tokens or coins that may be obtained.
