Agree and also in trading too, people are going to get addicted to anything that they think can give them money hence they'll continue to do that thing until they lose control and that's when they getting addicted. The difference between trading and gambling isn't that big as both of them can go horribly wrong when not done appropriately. Stop loss is for trading while cash out option is for gambling hence the similarities are there because you can look through history to get a better outcome from both your trade and your bets but not in all betting situations. The difference there is how trading can be learnt and improved on from continuous practices but gambling can't, you can only get better and it improves how you gamble but still the outcome isn't dependant on your wisdom.
