Could you kindly enlighten me on the question, "Are crypto airdrops halal?" I'm quite intrigued about this matter as it involves the intersection of cryptocurrency and religious ethics. Could you elaborate on the reasons why some might consider crypto airdrops to be halal, and equally, what are the arguments against it? I'm also curious to know if there are any specific religious texts or rulings that address this topic. Would you be able to provide some clarity on this? Thank you in advance for your assistance.
