Yes, we still need our lucky, which can support us to win the games. So we can see that both trading and gambling will need the luck to make money, but the chance to lose will be bigger in gambling than in trading.
How do you know that you will have a bigger chance to lose money in betting than in trading?
For me, trading and betting are the same types of work. You need analysis, money/risk management on both.
In trading, your profit will depend on the performance of the company or the currency owner. And in betting, your profit will depend on the performance of the team you bet on.
You can try by yourself
I don't think that is the same types of work. I prefer to do trading, but maybe you prefer sports betting, and that is no problem
When you lose in the sports betting, the money will lose, and you will need to search the other games and make another analysis, money/risk management on both while you still don't know when your luck will come.
In trading, if you lose and you still hold the coin, you will have a chance to see the price will increase in the future. As long as you can hold the potential coin, you can recover your losses.
And if you can search for the other coins which have the potential to make a profit for you. If you have good skills, it is not difficult to find that coins as we know that in the market will have so many potential coins which can increase anytime.
