I see a lot of bounty programs on the BCT, but I do not know which bounty program is good, there are many fraud programs. Can you give me advice ?
yes some bounties only for few weeks then over. we can recognize a good bounty from communication. you can directly contact bounty manager about the bounty. some are not replying too. if stakes are not updating for 2 weeks its a not a good one.
That may be true, when it is not updating after a few weeks then it might an indication of a crappy one.
On another note, you can just follow projects of companies and dev teams and managers whom you trust then you can be sure that you are in good hands.
Otherwise, you might as well do some research for yourself and yield good results.
