Since the year of 2018 the number of scam projects have started to increase, that is why investors and bounty hunters have lose their trust in new projects because most of the time the team members are making a lot of excuses when there are some delays in distributing their rewards and some team members have run away.
The rules on bounty are too lax, which gives scammers too many opportunities to trick investors, the most realistic correction and improvement in recent years has been the appearance of IEO, creating a protective shield for both investors and projects. But as soon as investors had a little hope of returning, the association with the poor exchanges then started the IEO process, which pushes investor profits into a deep pit, that's like a new scam, lose faith in the project and bounty again appears, bounty is probably hard to build trust back with projects right now
