You've already reached being a Sr. Member yet you still don't know the risks of dealing and participating in signature campaigns of bounty programs here in the forum? You should be aware that not all projects that runs a bounty ends up being successful as some can be legitimate but cannot reach their minimum quota for investment. Also, it is part of most campaign rules that the projects can often change their rules upon their choice and if payment from bounty is the thing that drives you here, I guess you'll find yourself wasting time on promoting projects that doesn't have any assurance of any outcome.
