There is a good chance some of the investors who was not taught the lesson of diversification are the same posters hunting us today 24/7.

They need to take a good look at themselves. Who pressed the buy/sell button? It is never to late to learn.

Some famous investors even have a strategy to buy low and sell high. How dare they!

HC Copper is full of bias and hidden agenda posters. Don't believe any of them. Anyone can tell lies behind an account to suit their agenda. Just ask our own OnesFate. It could be hatred, jealousy, paid work or something else.

Simple example in particular for OnesFate.

Checking for Biases and Hidden Agendas.
Whenever you consult a source, always think carefully about the author’s or authors’ purpose in presenting the information. Few sources present facts completely objectively. In some cases, the source’s content and tone are significantly influenced by biases or hidden agendas. Bias refers to favoritism or prejudice toward a particular person or group. For instance, an author may be biased against a certain political party and present information in a way that subtly—or not so subtly—makes that organization look bad. Bias can lead an author to present facts selectively, edit quotations to misrepresent someone’s words, and distort information. Hidden agendas are goals that are not immediately obvious but influence how an author presents the facts. For instance, an article about the role of beef in a healthy diet would be questionable if it were written by a representative of the beef industry—or by the president of an animal-rights organization. In both cases, the author would likely have a hidden agenda.
