Reliability of the source of information is not something easily achievable, because if it is not inside information, then everything really depends on interpretation and analysis. Some people do that better than others, that is why they earn on trading.
Having safe funds is of a high importance. After all, one should not trade with his last money, or with money that he can not afford to lose, because there is no way to restore this lost.
Even information obtained from the mainstream media often harms traders who decide to ignore information from other parties and end up making aggressive purchases as if they found the information earlier than anyone else. It is indeed not easy to absorb information about crypto or bitcoin. There are so many manipulations spread to deceive traders, in other words investors and traders buy while the information spreader is ready to sell.
Responding to trading must be as realistic as possible and not involve emotions. The point is that reason leads you in every decision. Because everything concerns finances that are not easy to get back if you have experienced a loss.
