But, people say that sports can be manipulated by mafia/casino for their own good.
So, which one is more risky? Skill-based gambling or trading? I think both of them have same risks because both of them could be manipulated, unexpected things could happen and many more.
I too agree that all gambling needs only luck to win money. But if your trade without any knowledge then it is also similar to gambling so don't trade just based on some tips. First, learn the basics of trading before jumping into it to make quick profits. There are plenty of experts lost money in trading so start with a small amount until you learn things.
