Follow the bounty management teams like Wapinter, Amazix, BXNTY. I am always searching campaigns from a great manager, because I have took part in a lot of campaigns and they were all awesome.
follow the manager is a good move and it's safe to and fro. The manager that has possessed big names certainly will also produce a bounty of good. But even this is not a guarantee because once the bounty manager carries the bounty scam and he is one of the great managers. other aspects such as its own analysis remain necessary in this case because the manager also will certainly make mistakes.
They are still human and not even a pro in in everything, we should double check projects legalities, some better project now were not even handles by famous manager but by the Ico team itself.
