Trading is speculation, but that speculation is not lame as it requires an approach. Gamblers have only one agenda: they are luck-oriented and lack a strategy and plan. So, I don’t think both are linked. There is a huge mindset and knowledge gap between the two.
A gambling trader is a person that trade without goal or daily trading journal. Some persons just keep trading without having a target or trading guide which is a bad way to trade. It is very easy for us to trade like a gambler during trading which is mostly based on guessing of the direction of a particular coin without having a concrete reason why we think the market will go in that direction.
In one or twice in our life time, we have fall in the category of trading like a gambler which may be during the time when we are still a newbie trader having the urge to trade like a pro trader with the kind of result they do have.
