#AirdropStepByStep An airdrop (in English: air delivery), in the context of cryptocurrencies, is a procedure for distributing tokens granted to holders of a preexisting cryptocurrency, such as Bitcoin or Ethereum, or to users of a specific online cryptocurrency exchange. Sometimes this is done in exchange for performing certain actions such as sharing on social media, inviting friends, installing an application, registering on a website, or filling out questionnaires.

All of this serves as an online marketing strategy to gain visibility and encourage the use of certain platforms, among other purposes. In the United States, this practice has raised questions about tax liabilities and whether they represent income or capital gains. One example of this is the one carried out by the company Omise, which gave away five percent of its cryptocurrency OmiseGO to holders of Ethereum in September 2017.
