Never the less, greed has been the downfall of many traders and the reason why, most tends to make a few and loose even more. Because, they want to get everything they see on the chats. Not trading gives them the impression of they are loosing or missing something and should they trade, they end up loosing. In essence, not trading could be saving your a** from loses.
Also Laziness have also contributed to the downfall of many traders. Many traders especially Newbies are so lazy to conduct their personal research before putting their money on a particular coin. Although, I understand that making research doesn't guarantee that you won't lose. But, I'm quite sure that it definitely reduce lost In trade. However, trades should normalize trading the amount they can afford to loose.
