Is money earned from buying a cryptocurrency at a low price and selling it at a high price using an automated bot permissible (halal)?

It is permissible to use a robot in trading fiat and digital currencies, provided that the exchange takes place in the same session, meaning that the purchased and sold currency enters the accounts of the parties within the same session. This is because currencies have the same rulings as gold and silver regarding the condition of immediate exchange upon sale, and the robot here acts as an agent in the processes of buying, selling, and receiving.
