So if I may ask, how can we identify this kind of fraudsters?
Take every unsolicited message, either requiring you to click a link, invest/deposit money in any platform, etc, as a scam, until you can prove that it is not. If you have that consciousness and eliminate greed from your mind, it'd be hard for you to fall victim to scammers.
That being said, it is advisable that you keep your assets offline, you can go for a hardware wallet, so that if you get unlucky and scammers come manage hack your device, dem no go fit steal your money, as e no dey online.
That is a candid advice, most at times scammers use mischievous means in form of links to try to caught people of guard, I've even heard of some links containing spyware that they could use to monitor your device and steal your password and paskey and that is why as a person into crypto you need to stay away from links as much as possible, especially unidentified links cause you could end up giving out your privacy to scammers.
