An Airdrop is a free distribution of crypto coins (or tokens) to a number of members ranging from the privileged few to anyone who requests it. This distribution is often carried out by the creator of the token or currency in question. The purpose of this free distribution of tokens is multiple for the company : to make it possible to be known through the advertising of the airdrop, to make it possible to greatly increase the number of users who own and use the token to ensure the sustainability of the company, or to thank its community for their follow-up and their involvement in the project.
