Are airdrops halal?

In the ever-evolving landscape of cryptocurrency and finance, the concept of airdrops has piqued the interest of many investors, particularly those who adhere to religious principles. The question that arises is: 'Are airdrops halal?' For those unfamiliar, an airdrop refers to the distribution of free tokens or coins to wallet addresses, often as a marketing tactic or to incentivize certain actions. The debate surrounding this issue centers around whether or not such free distributions of digital assets align with religious tenets. On one hand, some argue that airdrops are simply a form of promotion and thus permissible. On the other hand, there are those who contend that the very nature of receiving something for nothing may be contrary to the principles of honesty and fairness. As a financial professional, I am curious to know: What is the prevailing opinion among religious scholars and experts on the halal status of airdrops in the cryptocurrency sphere?
