And also scammers always rush on newbies because they can easily be deceived.
Scammers don't rush on newbies, they would attempt to rip off literally anyone, the only difference is some users are more easily accessible, cause they leave details about themselves all around.
• Email addresses while signing up for airdrops,
• Phone number and KYC information when using exchanges,
• Social profiles when joining bounty projects etc.
All these can be used to access and create a personalized scam, targeted against a user.
You avoid this by staying private, as much as is possible, and also being cautious; everything is a scan until proven otherwise.
