Why do people think that they're able to do this?
because they study markets, they learn how markets work, that is their work
see the candles, watch the chart all day and take a course of technical analysis that you will realize that if you look at the chart during the all day you will see patterns of trend reversals, falling trend and other patterns, you can know when will low and when will high, but predict the long run is another story very difficult to do and all predictions fail.
Is it because they think they can do it while no one else can? Let me know folks.
because they study markets
Just buy when everything is in red and sell if green.
good suggestion, but sometimes it turns red and then green but the price has not recovered.
for example:
someone buys bitcoin for the price of $ 10,000 and bitcoin drops to $8000 (this one in red) and rises to $8500 (this one in green), you will not sell just because it is in green.
Human is greedy creature so as long as they can achieve something profitable , they will do anything although it's risking their wealth
well, unfortunately in this world is full of people who have ambition exaggerated, people who are capable of killing hundreds of other people because they want gold, diamond and oil that is in the region that does not belong to them
No You are mistaken, in every market there is an analyst!
There is a calculation, everything can be proved mathematical.
There are many books you can read.
I agree
