So if I may ask, how can we identify this kind of fraudsters?
The first rule of avoiding scammers is when you accepted "there is nothing like free money on the internet", it's either you invest your money into crypto or you work to have it. If you can master this and remove greed from your ways, nothing will move you and scammers will find it difficult to get you because this is the easiest route to scam person in crypto.
There are other ways of scammers getting you as a victim, it can be through phishing scam, email scams, impersonating, romance scam, high return investment scams and malware attack. Apart from the recommendation I have given, make sure you practise a sekf custody, doing that will make your wallet from accessible because your keys will remain offline. If you remove greed and protect your wallet with outmost care, you will free from scammers.
The last but not the least, learn to be a private person. When a scammer don't know about your existence, they wouldn't be able to know how to attack you because they know nothing about you but if you are the type of person that will buy $100 worth of Bitcoin and announce it on your Facebook, WhatsApp and X, you will become a target for scammers, so learn to be a private person, it's part of ways from staying away from scammers.
