I do want to know if it's possible for a starter to gainfully earn from Crypto trading without having to go through a professional training.
Actually, it is possible, I have friends that are trading with their own skills, doing daily trading in several types of trading activities.
They are not professionals and not even educated in certain technology, program, or other types of this.
But, they are able to do it as a quite professional trader.
How can it be?
By learning. Learning will help you to gain some knowledge, at least you have the basic knowledge about crypto trading. This is not easy mate, because the crypto basic knowledge about trading also includes several elements, not only about the techniques, but also our management to be able to manage our own emotions, fund, and also control ourselves.
As long as you have a willingness to learn more about crypto trading from whatever you learn, you may gain more chances to be good in trading. You can learn from a professional trainer (it is much better because you will be guided enough), from YouTube, articles, and many more sources. But in this case, you must be selective enough to learn it.
