It is necessary to start from the most basic steps in trading because this market is very volatile and will definitely make you lose if you have no knowledge of trading.
And if even you have knowledge you should not be dejected by a few bad trades because I have a friend who is trading since 4 years or more and been like 2 years with crypto too and even he makes mistakes from time to time so yeah start from basics but yet don't be down by the initial loss trades.
I think newcomers need to take the time to learn or be able to watch some videos from the trading experts because they will definitely give you lots of new knowledge. In addition, it is best to use a demo account to get started so that you can avoid these mistakes later.
The problem with demo account is that when you know the money is not real you take very bold decisions while when real money is involved you consciously fear about losses no matter how confident you are after a good demo account journey you had because when money is real and risks are true you have to be more careful while when money is virtual and risk are also virtual you become fearless.
