Some beginners fall victim of attacks because they do not have the knowledge of what the social media environment is like. Apart from having wallets and cryptocurrency platforms it is very important for one to have knowledge about security and knowledge about how scammers operates to get victims.
That's the basic reason why scams happen. How do you think people scam other people? They use their vulnerabilities in their favor so that they can get something out of them while making the victims think that they are going to benefit from what's happening. Scammers are very sharp, they are very good at what they do because they have a lot of practice. There can be beginner scammers as well, but they can't get their plots done very well.
So, undoubtedly, a person needs to have at least general knowledge and understanding, so that they don't get scammed easily. If you get into a business but you know nothing about it at all, many people will come and scam you very easily because they know the market better than you, so they will make you think you are doing good business but in reality, they are scamming you.
