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.
There is some misconception of trading and gambling in your explanation, gambling and trading both involve risk but in trading you can still runaway from the risk when you are in doubt but you can't do that in gambling when you are in doubt expecting result, it will give you true of false. In short, in trading you can you use stop loss to reduce risk of market crashing but you cannot do that in gambling.
In addition, Bitcoin trader involves the understanding of the market and learning the indicators but gambling is not like that, you can't even learn gambling, individual opinions is what people risk own and if it's works, they withdraw the profits and enjoy and if doesn't it, which very bad thing to indulge on as a micro level.
Although there are some differences between the two, like most gambling depends mainly on luck. You play and let luck decide fate of the game, that is the risk factor, because the gambler doesn't have any control or influence to determine the outcome of the bet. Also a bitcoin trader doesn't have any control or influence to determine how the market swings, he takes the risk to trade his bitcoin without knowing the outcome whether it'll be profit or lose. The diffidence between the two is that a bitcoin trader can predict the market, while a gambler can not predict the outcome of a bet, except in sports bet.
So if a gambler where to go into bitcoin trading, do you think that the experience of taking risk in gambling will be an added advantage to face the risk of bitcoin trading?
When a gambler try trading the first time and gambly played like base on what he feels without putting others in contributions, it will take them 3 days to change from that lifestyle because they will lose everything before they know. A real gambler that loves trading will have to go and learn first before even checking for what trading is all about, what are the indicators to use and many more.
