What happens to those that are being distracted by those scammers is that they easily get carried away by hearing what they want to hear, you know there is always a direction towards whatever we give attention and that is what we may end up doing, that is to say one should be be more careful about what we give attention because a man might always want to will up doing just as his mind thinks, those that makes themselves vulnerable for a quick and easy money making mind sets gets excited on getting to hear what they want from those scammers, I call those scammers fishermen because they will always come with bates that will attract the fishes to be trapped.
When people listen to scammers they can easily believe false promises and forget what is real. What we pay attention to can lead us in certain direction and if we are not careful we can make bad decisions that are not good for us. Scammers most target people who want to make money quickly and easily and those people can get very excited and then get trapped. I like your comparison of scammers to fishermen who use bait to catch fish. It is reminder to be very careful and watch out when someone makes us offer that we did not ask for or that seems too good to be true.
Since we humans are greedy, scammers can easily take those opportunities and can also succeed. It is very difficult to get a person who has control over temptations and is realistic to get involved in a scam. The easiest way to identify a scam is to succeed very easily. If you are realistic, then you will realize that it is never an easy task to succeed in any work. The promise of success without effort means that it is undoubtedly involved in a scam.
Basically, a person easily falls for scammers due to lack of knowledge. In the case of Bitcoin too, many people fall for some scammers due to lack of knowledge, then the results are expected to make you feel completely calm and you consider Bitcoin a scam where Bitcoin has nothing to do with the scam. To enter Bitcoin, you should have minimum basic knowledge and try to gain as much deep knowledge as possible. It is wise to rely on yourself rather than relying on others, so that no scammer can take advantage of your vulnerability.
