if you are just a newbie in here, the bets thing that you can do is just to try to avoid having too much feelings while trading, and try to avoid being a greedy guy
Yes that is one way to control the emotional factor while trading. Adding about the skills, I would say a newbie should be well versed about the technology he/she wants to invest in and the market situation by which I mean to say he/she should have the perfect market knowledge. Also some knowledge about economics and finance would not be bad either.
Initially, a beginner needs to learn enough information to understand what exactly he wants to do. in any case, at the same time as theory, you need to engage in practical activities, but this requires a small start-up capital.
From the way I have been seeing the way newbies invest lately, I believe there is a lot of things every new investor need to know about capital management as well as how to research and understand their area of investment properly well before hopping into anything. The problem now is that a lot of people are too lazy doing all that, and they just want to get rich fast not knowing that nothing good comes easy and to get the best of anything, you have to be fully prepared.
