Hello everyone, I would like to ask you how to become a stable profit trader, what aspects should be learned from it, I have read some books, such as price behavior, but still at a loss in the real market

Keep learning new things, because trading in crypto requires you to continue not to stop at one reference. The point is that many things may make you more confused, but try to always start slowly, with minimal capital, and limit the number of coin buyers. You can adjust it with good management. Don't be surprised because trading with volatile assets is not always in stable profit.
