Airdrop refers to the distribution of cryptocurrency tokens or coins to numerous wallet addresses at no cost. It's often used as a marketing tactic or to distribute tokens to a wide audience. As for NFTs (Non-Fungible Tokens), they are unique digital assets representing ownership or proof of authenticity of a particular item or piece of content, often art, collectibles, or virtual real estate, recorded on a blockchain.

Regarding Nigeria, both airdrops and NFTs have gained traction in the country. Airdrops are used by various blockchain projects to engage with the Nigerian crypto community, while NFTs have seen interest from artists and collectors alike, providing opportunities for digital ownership and monetization of digital content.
