so now you can predict the market and guess the future price of Bitcoin?? Wow that's so cool, how easy it would be to make millions of dollars for you if you could do that, because you know the future and you have a very rare ability....
as far as I know, even a professional will continue to learn and learn even though he has been in trading for a long time... at first they also seemed to be someone who often lost, and now they can't guarantee continuous wins or even guarantee their predictions are 100% accurate... the market is really something that can't be predicted even for a professional... and to be able to make a profit, there is also a luck factor that comes along with the journey.
Losses are inevitable even for experienced people, however, with knowledge and experience, you get better over time because you will learn from your mistakes and improve. It's not possible for someone to predict every single move of the market, but why do you think people are profitable in trading? It's because they have learned a lot of things, and they can now, at least, predict the market sometimes through analysis that they have learned over time.
If someone says that they are able to predict the market every single time, they will be lying to you, but I think the guy above didn't say that. He learned and is now better at it, and that's how things work in general in real life as well. When we start doing something without any experience, we might make more mistakes, but over time, the mistakes will start to become less and less.
