This article is about trading, about halal and haram.
At first you have to know about Future trading and Spot trading. I think that spot trading is halal because business is halal. In business you buy something at low rate and sell them at high rate, spot trading works the same way. But in future trading you are not buying any crypto or currency, you are not investing. You are predicting that it will go long or short.
Secondly, suppose you bought some gold with 1000$ to sell it in high rate but suddenly you see that the price of gold has fallen in the market, you don't sell the gold anymore. When the price of gold rises again, you sell the gold, that's how spot trading works.
In future trading you are not buying anything, you are predicting like gambling, if you predict wrong you will lose your money, if predict right you will get alot of money. That's why I think it's haram.
If anyone has any feedback please let me know...
