So far, I have only relied on news information obtained from forums and social media and a little understanding of the foundation of price charts and market movements to make investment decisions in Bitcoin.
Then what is the way so that I can make a big profit ...?
actually you are on the right track. but you need to make sure the information you get. at this time so much information is circulating, but not all of that information is true and accurate. to make big profits, you also need to read and take advantage of the situation. like, when you have accurate information about the rising price of a coin, or the very good development of a project, chances are it will be very good for the future. utilizing information like that will make you profit.
Relying on information alone will not gonna help you, you also have to learn how to apply that as part of your strategy.
Failure to gain profit is like a kind of "giving up words" we should not feel like that as its normal to make mistakes in trading but what's important is we learn from it so we will improve overtime.
