We can inform you that basically, crypto airdrops are coins/tokens that are distributed free of charge or free of charge by digital asset developers who are selling their tokens.

In short, these tokens are distributed for free when you register and invite friends to join through your referral link.

For example, when there is one developer who is conducting a token sale with a total token supply of 1 million, this developer will share 50% for Airdrop, while the rest will be sold to holder buyers.

Therefore, these tokens can also be referred to as a kind of reward for participants who get involved and follow the project on the developer's social media accounts while helping in its marketing efforts.
