Scammers are everywhere. I have been scammed two times but it is not in the crypto field. Recently, when joining some airdrop campaigns of projects, I also got some message from scammers like hello, welcome to A, B, C... project. I'm here to help you...But I didn't pay attention to their message. They sent the wrong person because I don't have money to buy anything, I join airdrop to get tokens/coin for free

. One another reason that I have been scammed so I become more careful.
