Well, I must say for the new comers in cryptocurrency trading is to follow what has been posted in the OP, sure it's helpful, but there's just one of the many essential thing that helps you throughout your trading career, and that thing is called "experience".
There are actually a lot of trading tutorials in the internet and there are also video tutorials on youtube, which It is more easier to learn than learning from your own. There are a lot of learning stuff that are very important for your trading strategy, but then again, all of these will be effective once you have "experience".
So, those who planned to start a trading career, don't afraid to lose, and trade only what you can afford to lose.
Experience is really important, even though they follow the tips from the professionals, they still cannot make profit because of the lack of experience. Gaining experience is what we should focus in order for us to have better trading carrer. We can learn the strengths and our weaknesses by gaining experiences.
Then you're saying that we just need to face the risk head-on without getting ready?
Experience is what we earned from doing it in a long time but as a beginner, you will not have that experience that is why you need to depend on the knowledge that you have. You should educate yourself on what you will be facing, learn from those experienced traders and investors, read books and articles and don't stop unless you're successful enough.
