yes that's not true. if I know that it will not work then I will look for another place with the information that is suitable and certain, but the information coming from several people can be different so how to anticipate things like this, whether by relying on instincts on their own
You can't look into it from the beginning as if it's not gonna work. Unless you have sort of expertise or average experience knowing what good projects are. Knowing if a bounty is good or not won't only rely on your instinct, there has to be a basis whichever you join.
But if that's how you determine base through your instincts, I think some others also do that. But, what I'm saying is that it isn't enough to determine which bounty is good.
