in my opinion, I would definitely prefer trading than gambling. Speaking of gambling, I still gamble seldomly but I have had numerous unlucky encounters with sports gambling to stay away from it. Humans are the most complicated creatures to predict. Instead, I prefer casino games. Since there is no emotions but luck it will always be my choice of gambling.
The both things you have mentioned carries risk and you can lose your money while you’re doing any of these, although the way they work is totally different; I would say that casino and the rest of them are relying on luck while the trading is all about doing analysis and knowing what can be the outcome of the market next, but you can’t be 100% sure that that it is, but you will know that there is the possibility of that such thing happening.
So the both of them has risk, but I do hear more of bad stories when it comes to gambling, although I have also seen people who were very lucky and won huge money that changed their life, but I wouldn’t say it is lucrative. Just go for trading, but you can still be trying out your luck in casinos if you wish.
