Yep. I think trading could be addictive.
It is easy to get addicted to trading as well, especially the form you mentioned. People take high risks to make money faster, and once they realize they can make money, they try more. Even if someone loses money, they try to recover the funds by trading more. People eventually get addicted to trading.

Now, I believe there are a couple of signs of addiction. The traders usually do some research before they open a position. But if someone gets addicted, they focus on making quick money and open positions without doing research. Also, addicted traders do not have a session plan. They start opening positions even when they are travelling, eating, or doing other activities. While the non-addicted traders have their dedicated time for trading only.
