We all have different opinions about this but for me it depends on how you see trading. If you are a trader with a psychology of a true trader, you most likely have good patience and calm mind on your trades, you won't chase losses or having rush decisions, every step is planned and has logic behind it. It's unlikely that you will get addicted to it since you have a mind conditioned to do calculated moves.
The way most people see trading is completely different from how it’s suppose to be. Some people are into trading because they are after quick profits, people like this are not always having patience when they trading, they don’t even have proper knowledge about trading. Immediately they start losing from trading, they get frustrated and will want to recover the amount which they have lost.
Some of them even go to the extent of borrowing money just to trade, they are always thinking if they make some profits, they will return the money which they borrow, if people like this end up losing money, they will be frustrated, and will want to do everything possible to recover their loss. People like this will end up getting addicted to trading, and they going to lose more money.
