While gambling and trading may seem similar in some contexts there are big differences when it comes to responsible management. The reason you see many people who are unable to control their gambling addiction is probably because the inherent characteristics of gambling are particularly conducive to addiction. Those who are able to control themselves in trading are likely to focus more on knowledge strategies and long term goals but there is also the risk of irresponsible behavior and addiction in trading. Responsible behavior and self-control are crucial in both gambling and trading due to their fundamental nature, controlling gambling addiction can be difficult for many people.
In terms of self-control, both trading and gambling will be very important. Because when traders or gamblers do not have it, the risk of addiction or excessive trading and gambling can occur. Gambling may be more likely to make gamblers addicted, it is because of the adrenaline and excitement of the game that allows gamblers to forget their limits.
But for me, both gambling and trading require knowledge for beginners before starting. Trading can be worse if the person doing it does not have a good understanding.
