Is it permissible to trade cryptocurrency on margin, provided the position is closed before overnight financing fees are incurred?

It is forbidden to trade currencies on margin for two reasons:

1. The presence of a usurious condition: The rollover (overnight) fees on margin, which is a loan from the company, are considered clear and forbidden usury (riba). It is not permissible to accept this condition even if the client intends not to roll over. 2. Combining a loan with a compensatory transaction: This is represented by the company combining the provision of margin (the loan) with taking a brokerage commission (trading). This falls under the ruling of combining a loan and a sale, which is forbidden by Islamic law, because "every loan that brings a benefit is usury."

For the transaction to be permissible, the margin must be completely eliminated, or the margin must be a benevolent loan (qard hasan) without commissions or conditions.
