Trading with leverage is just an option you can make a trade with low leverage or zero leverage but if you have a small amount of money only and you want to make a trade its not profitable at all, else you will put leverage so you can get a higher chance of profit. Always make a trade which you can only afford on it. Lossing a trade does not mean you lose a profit still at the end of the day number of earning on every trade is the one you gives a good outcome. So base in my experience safe leverage is with the range of 25-75x.
Is this almost similar to Future? Because I've never done leverage. It seems tempting if this is similar to futures. But if it's the same it seems the risk is very big. I once did Futures trading but I gave up because if it goes down deep without SL then you will lose money. I am currently comfortable playing spot trading. Maybe I'm just uncomfortable because of the unstable emotional factor. You have to be able to control your emotions and that is very difficult. Because I've tried many times and it always failed.
