Which one is the best depends on everyone, futures trading will be very good when that person understands and understands how to analyze the market, determine when to enter and exit and is wise enough to use leverage. Using a high enough leverage will make the risk bigger, but when the target price is reached, there will be lots of profits to be had. and when gambling like slots there will be no predictions made, all based on luck in each round. and sports betting can do an analysis on each club that will be supported. Gambling is more about entertainment for me and placing minimal bets with and allocated, whereas futures trading is more about growing my assets.
Gambling and future trading is based on the same concept of the betting and prediction.In gambling we predict the exact option which win,but in the future trading we will predict the market movement.But the market is not possible to predict is the real fact.In every two days the crypto market reverse to opposite direction.In future you have to reduce the multiple of profit or loss calculated.If you make the mltiple between 10-20x then it won't affect the invested money.The future also need to fix the stop loss option to avoid of the big loss in the future trading.
You are right that futures trading is a bit safer, but the only thing that makes it so is the ability to exit, losing only part of your money, not all of it like you can do in gambling. On the other hand, the profits are also much smaller. You rarely get x2 right away. Usually it's a percentage of your investment. So instead of winning 100% or losing it all, you win 10% or lose 10%.
Analysis doesn't help much because the market can be manipulated and you don't own the asset. You bet on a prediction and never have anything but a promise of payment from the fund.
Future trading is not a safer one,until you made the stop loss.The fact is most of the new people don't know how to do future trading.So they won't do the stop loss option,but the loss will exactly loss as compared to loss everything.Gambling had some risk,but it's the game and not the trade.So we can earn huge money from the Gambling.But the future trade is entirely based on the good skill and the experienced trader will handle this future trading.
