You both are right about trading and at same time wrong reason because trading doesn't only make people poorer neither does it only make people richer but rather trading does the both depending on how you go about it or if your strategy is really working.
You are actually right
sotelorene, becoming richer or poorer in trading or gambling depends on the individual but what I can say in this conversation is that people lose more in trading or gambling than gain. Because majority of people that did trading don't have a good record of profit they have made for the past few years they are into trading in comparison with the long term investors. that is why people always talk ill word about trading/gambling, But that doesn't mean trading is that bad. But If a person has invested lot in bitcoin and have achieved his desired amount of btc in his portfolio, such person can decide to use %10 from his profit and risk it, but should not be first priority but the last thing to gamble with.
