Trading can be addictive, but not like gambling. Before someone gets addicted to trading, that trader must be a profitable trader, and since you already have a profitable trader, even if you are addicted to trading, then I will say there is not much trading since you have the knowledge of what you are doing and you are not predicting the market; ..
It doesn't matter which trader is profitable or unprofitable, since addiction in both trading and gambling is based on dopamine, which is released not only when winning, but also when waiting for a profit.
