You really have to start from this because you can’t be good in trading if you don’t study how it works, don’t just think that you can easily make money in trading for one week without any experience or knowledge about trading, though this is not a hype but a proof that if you do your best to analyze, you can be more profitable.
You are right, in fact, to have a week and start trading without having previous experience is a very high risk, the truth is that I would not get involved, when I was a rookie what I did was watch many technical analysis tutorials on YouTube and they made it possible for me to make decisions based on this, however when I made those decisions it did not go so well, because I did not know well the concept of the market stages such as accumulation, distribution and each trader handles these concepts according to the timing of the trading, The only way I learned to understand the market better was when I read Wyckoff's books and Jesse Livermore's teachings.
I do not like to read things because I can't learn it that way, so I watched a lot of youtube videos myself as well. There were a lot of different opinions on how to trade, some people bought based on different indicators and some others did it some other way so basically when you watch dozens of different people, you learn dozens of different ways. What I ended up doing was trading based on each of them, and use those different methods to see which one is right.
The best outcome happened when most of them were right all together at the same time but that rarely ever happened, like whenever there is a crash of 40%+ in a single month, buy bitcoin, because 99%+ chance it will go up in the near future, which has always happened aside from 2018 and even then we managed to recover pretty well later on haven't we. So, learning by watching and repeating does help you out a lot but takes a long time.
Of course, yes, in fact when I began to try to learn, my first school was YouTube, and some time later when I realized that the information was very unstable I stopped seeing because every time I operated I lost, then I got the perfect refuge to be able to have arguments to know what type of information serves me or not, currently I see many videos on YouTube, but I quickly identify who sells smoke and who gives real information and that I can extract, especially those YouTuber who give technical analysis courses , and those who are dedicated to giving signals, which have a very low probability of being right.
