Lets just point out on whats being mentioned on the article.
=Overtrading from being overly confident
=Inadequate capitalization
=Not adapting to market conditions
=Being motivated by greed
I highly agree with these points and one thing which is important to avoid is that on that #4
yet any actions driven or motivated by greed will really result into a disaster.
On that number 4, I think we should used our logical thinking here and not to be carried by our greed. Number 1 though, I must say that I'm guilty as well, being confident that I wouldn't lost in this market, so it's a hard lesson.
Number 2? I guess we can start with small capital and try to get it multiply over time. I believed most of us did that, We begin with small capital we earn here (sig campaigns, bounty hunting) and used that as a stepping stone. Then we trade our earnings, and make the best out of it.
Because being too confident is not always good in all aspects. It can bring you to failure for rushing something that you shouldn't. Remember, always take things slowly because they say that "Slowly but Surely".
Market capitalization is a natural thing, you will make your money grow from smaller to big amount of profits. After that we always enjoy wise trading that will also help us to have profits.
Loss are the effect of greed and rushing things. You should take your actions with a correct thinking and mind manipulation for you to know the next actions that you must do in the market
