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.
