You don't need such knowledge, if you are careful and are not greed, you can avoid scam very naturally.
And you shouldn’t limit your learning either, because scams these days are getting more and more convincing.
Scammers are also evolving to match the trends and demands in the investment world. So if you stop learning, your knowledge might become outdated and that’s exactly what makes people more vulnerable to scams like these.
Of course, we should not limit our learning because knowledge is the key, it is power. But to avoid falling into traps and scams, we just need to control our greed well, then no one can deceive us. When it comes to scams, it is mostly due to greed rather than outdated knowledge.
A knowledgeable person who is always updated with the latest news can still fall victim to a scammer if they do not control their greed. But ignorant people will not easily become victims if they are always vigilant and not greedily tempted by the beautiful things that scammers draw.
