I base my question about whether a gambler can become a good bitcoin trader, because both of them share one factor which is risk. A gambler is a risk taker, he stakes his money without knowing the outcome of the game that he is about to play. There is no guarantee that he will win, yet he goes ahead to play, knowing fully well that he can lose his bet. Same thing with a bitcoin trader, he goes ahead to engage in trading knowing fully well that the market can turn around negatively for him, making him to lose his bitcoin. Yet he goes ahead to trade in the hope of making profit.
One thing you need to understand that is even if trading is all about loss and gain the risk in trading and gambling are not the the same. In trading people who learn trading very well and understand it better stick to it and earn from it as source of income, but I gambling no matter the experience one have their is no guarantee that winning will be constant. I think a gambler who understands trading very well and it rules can still trade with a different mentality from how he gambles. Their are many factors that gives gambler too much confidence that they will always win that is why some gamblers keep playing without winning.
