Yes more reason to be active on bull run as people are engaging on investment. People or users who are into airdrops and investment must be cautious cause there are lots of scams lingering around especially on social media. On Twitter we can see those styles already when there are projects announcements and they pop up like the real one and youll get hit if you dont check it carefully.
